I don't think you are the only one, at least I noticed many of the same
problems.

I don't know what it means, but I had the same problem. ST-Guide can't be
used at all. As soon as it is selected in the desk menu, it crashes.

I don't know what JCLKTOOL is but I still got these freezes without using
that program.

I don't know how to debug freezes, but if anyone comes up with some
suggestions which don't require a really in-depth MiNT knowledge then I
will also try. Memory protection would be very good if it worked well.
