We have built a VB program that controls the opening of acrobat and
monitors its usage.  On a number of the users machines (not on the
developer machines) if a user both types in a field and drags the PDF
with the mouse at the same time the Adobe crashes.  We have tried to do
this to one of the PDF forms outside this program and it does not crash.
The version of Adobe is 4.05, the version of VB is 6.0.  The operating
system is either Windows NT 4 or Windows 2000 (it happens on both).  We
have tried with different amounts of memory (from 80 MB Ram - 260 MB
Ram).  There is a custom plug_in in the program.  Consistently none of
the developer machines crash, but user stations do.  Vb error catching
catches nothing and there is no error in the logs.  I suspect it is
something in Adobe.  Does anyone have any ideas on this problem?
