cant create window of class wxwindowclassnr

[Manager]

Hi List

I am working in a browser plugin based on wxWidgets. When I try to
initialize the GUI on the frame constructor, this message pop up.

Can't create window of class wxwindowclassnr(error 1406...


If I try to load the same code "onpaint", there is no problem at all. I need
to subclass the onpaint from another library (OpenSG) and so, I can't use
the wx OnPaint to that. Anyone has a tip? My env is WinXP Sp2, VC 2005 Pro,
Wx 2.8.6.

Regards
Rafael
