1. Run Geometry sample,
2. Maximize application,
3. Close dialog,
3. Invoke Point from sphere,
4. Restore MDI child window,
5. Change background color of MDI child to green,
6. Minimize - maximize application
or Alt-Tab switch between applications.
Result - the MDI child window has its original background color (gray), the contents is not redrawn.
I met this problem in OC4, hopped it will be solved in OC5.
Is there some way how to go around that?
