ATL event_receiver in a static library

[superema]

Hello

I wanted to put an event_receiver class into a static library, but I always have this error:

mfcs90ud.lib(dllmodul.obj) : error LNK2005: _DllMain@12 già definito in TD3DxMouse.lib(TD3DxMouse.obj)

when I link it to my MFC app.

What should I do??

Thanks
