I found another problem in the same applications described above. The only one change in above scenario is that my DllA extension DLL is now using another extension DLL in which classes are exported. The problem is that my application gets hang.


I 've verified all the things

* dll path was correct
* LoadLibrary returned not FALSE
* GetProcAddress returned not NULL

All the above are OK.

When I debugged that application, inside the DoModal() there is RunModalLoop at this particular point applications gets hang.
