Hi folks,
Without straying too far OT, I think it needs to be said that Win9x/Me
do not handle resource management or systems scheduling very well. If
you have something "not responding", it is likely because the OS hasn't
gotten around to dealing with it and not because the process has had an
error.
Cygwin is resource heavy as are most third party apps (such as
ZoneAlarm) when it comes to Win9x/Me. Add too many processes and the
OS will effectively freeze...guaranteed. Doesn't seem to matter how
fast the cpu is. Nor does the amount of ram make much of a difference
in reducing the frequency of such occurrences.
Peace,
Paul G.

Nothing real can be threatened.
