wxPython Demo bug

Hi !

In my machine I opened the wxPython demo yesterday morning.

Many times I start it in morning to if I need, I can quickly see the examples.

In the afternoon of yesterday the grid demo drop many errors.

I see this error in the bottom log window of the grid demos:

OnMaximize
Debug: ..\..\src\msw\dc.cpp(2156): 'StretchBlt' failed with error 0x00000005 (a hozzáférés megtagadva.).
Debug: ..\..\src\msw\dc.cpp(2176): 'BitBlt' failed with error 0x00000006 (a leíró érvénytelen.).
OnMaximize

The used version is wx-2.6-msw-unicode, and Py 2.3.5.

I only want to report this bug.

Thanx for your read: ft
