Problem with graphic interface (some buttons don't woks...)

[DarkGod]

I have built VLC under Windows XP using Cygwin but I have a problem with graphics interface. VLC starts with skins2 interface but the "preferences" button" and "add item" botton don't work.
Moreover, the command
vlc -I wxwindows
don't have any effects, and I CAN'T USE wxWindows interface!
I have built some different versions of VLC and snapshot, but the problem is the same.
what I would have to do??
Thanks a lot!

I have *partially* solved the problem.
I have re-installed all the library and VLC, using a VERY OLD library version (contrib 2004-11-01) and now the wxWindows interface works correctly.....
.......But WHY?!?
It's very strange...

I would like to use a more recent version of library...

Somebody have any ideas?
