In my application, if one dialog is open, the taskbar icon shows as the icon
of the form.  If multiple dialogs are open, then windows groups them under
one icon in the task bar, but the icon is blank.  The application definitely
has an icon, as is show by the compiled executable.  Does anyone know why
it's blank?

Do the dialogs also have the same icon as the app?

No,  does this make a difference?

This might be your problem http://support.microsoft.com/?kbid=818110 
seems like it has been fixed in SP2 also came across this intresting
article http://www.mvps.org/sramesh2k/taskbargroupicon.htm

One other thing, it seems strange that dialog windows show up as
seperate windows on the taskbar in the first place, to avoid this you
can use the overload of ShowDialog that takes a window as a
parent.Something like this

form.ShowDialog(this);

I use the Show instead of ShowDialog.  I'm not sure if it's overloaded.
Thanks for the links.
