While Wine log might be enough for me, for less tech savvy users it is a 
mistery, and in most cases they do not even know it exists. Log message 
seems an easy solution, but a dialog box might be much better for a 
'customer base' of such feature. Such dialog should be shown only once 
per program run,

In some cases (.NET?) such deature could even offer an auto-fix (using 
winetricks?).

Still, apps loads some DLL, ant this can be intercepted. I do not know 
enough about how OLE works, but maybe a sister 'Known OLE keys' feature 
might me usefull too :)

This could be handled by some kind of configuration (xml?) file.
