Dan,
The bug is in j.exe psel command (as you suggested). A j.exe is at the
web site that fixes this bug. I'd appreciate it if you could test and
verify the fix problem. This j.exe contains other J602 changes (fairly
isolated areas) so should be used with a bit of caution, but I believe
it should be stable and not introduce problems.
