This is almost certainly a known problem with 3.1D on the 5000.  The problem
has to do with a race condition which causes an infrequent and random hang
that can occur during cursor loading.  There's a patch available from the
Support Center in Atlanta.  Perhaps somebody else can tell you the exact
procedure for getting this patch, but I imagine that any DEC SW support 
person knows how to get it.  (Sorry to be so vague, I can get more info
on the procedure for this if you like.)

Upgrading to 4.0 does certainly fix the problem as well.
