Strange. Well, it works, and you can alias enigma to include
the export-command, I think.

What exactly it does, I don't know. "DGA" means "Direct Graphics
Access", which is deactivated with the above command. But what
it has to do with the mouse-grabbing, I honestly don't know.

Good to hear it works! :-)

I wish you some more fun with Enigma, if you find problems
with a level, don't hesitate to ask on the forum:
 http://www.mag-heut.net
You're welcome.

Definitely, I'll add it to the FAQ. Update will be with the new LotM,
in two or three weeks.

I looked over the devel-archive and found some mouse-bugs, including
this one. But I misread, then neglected it. However, there was no
solution given either, I had to go through sdl-bugzilla.

Ah, yes, I didn't notice that either.
