A new Graal version has been released.
The list of features/bug fixes is attached to
this post.
Because there was a big bug in the
first version (script command destroy didn't work)
and there were incompabilities with Windows98 we
already needed to release a bug fix release,
short v2.13rev2. Get that version if you have downloaded
the first version. The Graal.exe should work on
Windows98 now. The setup.exe still has some problems
on Win98 which will probably be fixed soon.
