Thanks Mathias, that kind of worked, but I get no *grep* buffer.

Beside that it opened Wink for me. Looking at the code I can't see
that it could do that - but it does. Anyone understand what
happened??? (Wink is a w32 program for making screencasts. Very good,
but unfortunately not GPL. I have used it for nXhtml screencasts.)
