Dear Support Team,

I have a problem with CExtTabMdiWnd and I can reproduce this with the ProfStudio sample but not with the DrawCLI sample.

If I activate a window by click on the caption bar of the window and release the mouse button and move the mouse, than the window move to the new mouse position. But this happens only if you activate a inactivate window. And the tabMdiWnd switch very slow to the new activate window. This is not the case by the DrawCLI sample. The change is much faster. Do you have an idea?



Regards

I have

- Windows 7 and Windows XP

- VS 2008

- ProfUIS 2.90



I have checked again, and it happens only in the Office 2007 and Office 2010. If you run the ProfStudio sample and create 3 or 4 new (File->New) ProfStudio child windows. Than go to Window->Windows... and in the Window Manager dialog select all child windows and click on the overlapped button. And now if you change a window by clicking an inactivate window on the caption bar (release and move the mouse quickly) the window will move to the new mouse position.

This issue can be reproduced using Prof-UIS 2.90, debug build and slow computer. We cannot reproduce it with 2.91. We used 30 open MDI child windows in our tests. When you use a fewer MDI child windows, you cannot reproduce it.

We cannot reproduce this. We tried UI themes with skinned and standard window non-client areas. Which versions of Windows, Visual Studio and Prof-UIS are you using in your tests?
