ApplicationCallWndProcHookProc hangs

created 14 years ago

I've moved my projects from Delphi 2006 to Delphi 2010. By that, I needed to update to the newest version of the used components. (e.g. DevExpress Build 54)
Now I have a problem. Our program starts correctly and gets visible, but after that it will be frozen – no further repaint, no user input – you have to kill it with the task manager.
An analysis of the program run shows, that the program is trapped in a repeatedly call from USER32.MoveWindow to ApplicationCallWndProcHookProc of the cxContainer unit – always called with the same call stack. No other code will then be called, the program is frozen.
Please have a look at the attached screenshot, to get more information about the call stack and the hook procedure.
Can you help?
