I can I have this a lot.

Have seen it happen with references but I have also re-created it (on
a semi daily/weekly basis this shows up).

What I have noticed:

 Seems most likely to happen in Multi project solutions of mixed
types.  Mine has 2 C#, 2 vb, 2 deployment projects  a merge module
(dependent on project items) and a Setup, and 22 C++ projects.

 This seems to happen to most often when the following conditions
exist,

I have C# or VB designer -and- code open, I open several C++ files.
I right-click to close the designer windows or change to another
non-designer window (using tabbed layout) and then Maximize or restore
the window.  It will then generate a separate phantom type window on
the other monitor.  Also sometimes happens when I use the taskbar
Quick Launch bar Show/Hide Desktop button.

Like stated before it is clickable window (this is a interesting trick
BTW) I can use the minimize button or maximize from *BOTH* windows and
the close button.  The contents are not drawn and the color is the
normal window background.  

Using the windows key Minimize all or cascade windows (moving it onto
the monitor it's displaying on)  it sometimes goes away.  Also
reducing the machine load (i.e. stopping processes closing apps)
sometimes makes it spontaneously disappear.

 Happens most often when machine is under 50%+ processor usage and
the IDE is either compiling or another process has the CPU (like
another compiler (not VS.NET)), but I have had it happen with an empty
IDE too (though this is rare).

Info :

Software :

 WinXP SP1,all SP2 released content installed
 Full MSDN copy of VS.NET 2003 with all options installed
 SQL Developer edition installed and running
 PSDK is most current from PSDK Update site with everything installed
 Virtual PC 2004, running W2k test (nothing but base SP4 OS and our
software package installed).

Pentium 4
512mb RAM
60gb HD
ATI Mobility Graphics chip.

Pagefile is 1GB currently(though this is controlled by XP)

If you need more info let me know what and next time it happens I can
pull anything you would like (if you give directions or link to them).
Willing to consider remote debugging access to machine have high speed
connection and can use T1 if needed.

John:

I think that Self pretty much has it covered.  All I can add is that mine is
not a mixed solution:  This solution contains 18 C# projects -- all class
libraries except one (winform app).  The behavior that I see pretty much
matches Self's.  There is no 100% repro, but it does happen several times a
week.  Adding references is where I get it most.  However it might have
something to do with source control.  It usually seems to happen when a
source control "checkout" dialog is automatically displayed-- like when you
modify the contents of a controlled project, or when you attempt to edit a
source file that you do not have checked out.  I think that I have also seen
the effect after refreshing my project from source control.

rights.

My situation is similar to the others:

Dell 4500 with two video cards (NVIDIA GeForce 4 MX420 and ATI RADEON 7000).
Both montiors set to 1280x1024, 32 bit colour.

Solution has ~30 projects, all C#, one setup project.

I notice the "bonus" window when building the solution.

No source control integration.

Ladies and Gentlemen

Sorry this has taken so long, but it's been difficult to get much attention
for the problem without an in house repro case.

Our best guess at this time is that you are not using the default order for
your monitors.  Under those circumstances we sometimes see graphical
anomalies because the coordinates of the second monitor are now negative,
and some of the windows that the IDE creates are hidden by creating them
specifying a negative origin.

You can check this by opening the display properties dialog and selecting
the Settings tab.  If the 2 screens are not displayed as 1  2, try changing
them to that configuration and see if the hidden window problem persists.

If you are experiencing the problem, please check and see if this resolves
it.  If not, I need to know so that I can take the problem to the next step.

Thanks,

Hey Guys,

Thank you very much for bringing this to Microsoft's attention.

After looking at this thread, I found a bug which describes to be very
similar to what you guys are talking about.

Please let me know if you think following is the same behavior the issue
discussed here.

Description
==========
When using the Visual Studio.NET IDE on a dual monitor system, occasionally
the main application window will attempt to redaw on both displays.

Steps to reproduce problem:
(These steps may not always reproduce the problem)

* Open Visual Studio.NET.
* Move the window to the Secondary Display.
* Maximize the window.
* Open a project.
* Open a source file inside that project.
* Switch to another application in the Primary Display
* Click on the Visual Studio.NET IDE in the Secondary Display
* Attempt to click and drag to highlight some code.
* IDE becomes unresponsive.
* The IDE frame window is redrawn in the Primary display as well as still
existing in the Secondary display. However, the window in the Primary
display will have a solid white client area.

Note:
Program can be closed via the system menu button on either display.

Workaround:
When this happens, minimize both IDE windows. Then restore the window from
the taskbar. The IDE will resume it's position in the secondary display.

We are not able to reproduce this issue for next version of VS .Net.

Are you able to reproduce the behavior on VS .Net 2002 or 2003 using above
steps?
