Maximize Form Issue

Brandon

Hello there.

I'm currently working on a moderately complex Visual C# windows application
that I have run into a bit of a problem on. To start things off, the
application has normally been run under Windows XP with the theme mode set to
Windows Classic (disabling the newer XP theme) at a resolution of 1280 x 1024
on a dual monitor system. The application has two sizes; one is roughly 800
x 600, and the second is full maximize mode. It is not resizable by
handle/window dragging. Under my normal operating conditions, I can maximize
the application with no issues. But it has come to my attention that if you
are instead running Windows XP with the new XP theme mode that the maximize
functionality breaks. Instead of going full screen maximize, the application
instead moves into the upper left hand corner and locks in that position in
its original size. Stranger still is that if I start the application in
Classic Theme mode and then switch the application to Windows XP mode without
reloading the app I can maximize just fine. It is only if I run the
application while already in Windows XP theme mode.

That is really all the information I have. I am curious if anyone else has
seen this issue, or if they think this could be an issue with docking,
anchoring, or locked forms. As of now, the form is not locked obviously
works as it should under the non-themed mode. Any assistance would be
appreciated.

I assume that it achieves this by offering the maximize button on the
caption bar, but not offering the resize handle on the lower right? I'm
also guessing that there's no special code in the application to make
it react the way it does: just a default form size (which the user
can't change) and the option to maximize?

If all of this is true, the only thing that comes to mind is the
MaxSize property of the main form. What's that set to?
