i must have missed that, that looks like a good solution. time to check

When you think it through, it does appear so. Why would an application 
that doesn't exist need grab. Although i don't know the full mechanism 
behind grab, so it might be that there is some reason why this hasn't 
been fixed.

Oh well, i'm looking forward to xouvert, somehow i have lost my faith in 
XFree86.
