Hello ProfUIS-Team,

in v2.82 there is a difference in the behaviour between different samples concerning the maximized view on a second monitor (extended desktop mode): Some examples work always, some work never, some work sometimes but only under specific circumstances.

For example, the SDI_DynamicBars works always perfect (even with persistence), whereas SDI_DOCVIEW never allows maximizing on second monitor.

RibbonBar sometimes allows maximize on second monitor, but after new start application maximizes always on first monitor instead of second.

Any idea?

Best regards,

No, it’s just the WinXP standards running, without additional buttons. Other MFC or Win32 programs maximize without any problems. Therefore I’ve thought it could have something to do with some wrong settings inside ProfUIS.

Do you have any installed software that modifies the default desktop window behavior? Some versions of ATI/NVIDIA driver software may embed additional buttons into window captions, provide multiple desktop support etc.

Hmmm, difficult to say what’s wrong ...

We’re using the following system:

Windows XP (SP2)
NVIDIA GeForce 8600 GT
1680x1024 - left monitor (primary)
1024x768 - right monitor (secondary)

Best regards,

We cannot reproduce this problem with any of our sample applications and we never received any problem reports about losing the maximization ability on secondary/primary monitors. We used Windows Vista Enterprise 32-bit with and without DWM enabled, two 1024x768 monitors (left is primary, right is secondary, all screen coordinates are positive).
