Hello, I guess it happened after some MS update but I can't start X anymore (from an rxvt-native console since clicking the desktop icon doesn't display anything): $ startxwin.exe

Knowing which dll didn't load could help, I guess... What's annoying is the fact that this used to work really fine up until about 1 week ago... Thanks! Denis
