I've been using VS tools for years and have never seen this problem before.  
I just set up a new dev box with a fresh VS .NET 2K3 install.  I'm having
this same problem with all my existing solutions, and any new ones I create...

I can't modify any of the project dependencies or Configuration Manager
settings.  If I bring up the Configuration Manager, for example, everything
looks OK....none of the popups or checkboxes are greyed out.  But if I try to
click on any of the controls...like to enable/disable the building of a
particular project, nothinig happens.  Same thing with the "Configuration"
and "Platform" popup menus.  The same thing happens when I try to change a
project's dependencies.

I've tried building projects and solutions from scratch, throwing away user
settings, checking for updates, but nothing helps.  None of the files in
question are write protected.  I'm using the same solutions that worked fine
on my old box.

Can anyone tell me what's going on here.  This is driving me nuts!!

TIA for any help,

Steve
