Strange Problem with CXTPSkinManagerApiHook

I'm using the Xtreme ToolkitPro v10.4.2, running on Windows XP.

 

I'm using the same bit of code in a standard MFC Application and also an MFC OCX.  Both the Application and OCX are using an MDI Document View.

The MFC Application is working correctly .   But the OCX is causing random problems and when testing in using the VC6 IDE the OCX stops with an Unhandled exception in iexplore.exe(USER32.DLL): 0xC0000005: Access Violation.  Here is the content of the call stack window :

 

USER32! 7e446a71()

USER32! 7e43f12a()

USER32! 7e44f76c()

CXTPSkinManagerApiHook::OnHookDefMDIChildProcA(HWND__ * 0x00230ef0, unsigned int 5, unsigned int 2, long 31720421) line 853 + 21 bytes
CMDIChildWnd::DefWindowProcA(unsigned int 5, unsigned int 2, long 31720421) line 440

CMDIChildWnd::OnSize(unsigned int 2, int 997, int 484) line 643
CChildFrame::OnSize(unsigned int 2, int 997, int 484) line 279

 

I've also tried this with the TestContainer, which resulted in the same problem

 

Any ideas?

 

Thanks

Firstly thanks for getting back to me..

 

I've upgraded from 10.4.2 to 11.1 and recompiled both the application and OCX.

 

Unfortunately, I'm still getting the same problem..

Here is the call stack again:

Any ideas?
