[MSW 2.8.6] DLL & event handling

[Luca Cappa]

Hi,

are you linking your executable and your DLL *statically* to wxWidgets? In  
that case it is expected to get that wrong behaviour, because for example  
all the static variables are now replicated in both images. Instead you  
should link dinamically to the DLL libraries of wxWidgets (if you are on  
MSVC, when you compile the "DLL Release" configuration you will find those  
DLLs in wxwidgets\lib\vc_dll along with the ".lib" files to link  
implicitly to them).

Greetings,
Luca
