bad vtable since wx2.8 on msw

[Riccardo Cohen]

It did not work, I generated a project with dialogblocks, and the 
problem was still there.

I found a solution : all my virtual members were moved to "handler" class :

class mywin:public wxWindow
{
myhandler *handler;
};

class myhandler
{
mywin*awin;
virtual void myvirtfunction();
...
};

It seems that my classes have problem to inherit from wxwindow, my 
virtual functions are all in mess. By the way PCLINTv8 complains about 
many classes in wxwigets that has non virtual destructor... Don't know 
if there is a relation... (see list below)


Anyway thanks all for your help
