I just migrated my VC++ Project to MinGW and recognized, that I've lost lots of Vistas native Look&Feel.
When I compile it with VC++ everything looks like Vista, but when I use MinGW, most things look like the classic style, just some things look like Vista:

left: VC++, right: MinGW
But! When I compile the wxWidgets template project, everything works and looks fine.
Does anybody has an idea how to fix this?
