Thank you for your response. I am aware of problems described. I just
added try, catch, finally statement recently after getting this error
for a while and I added code to destroy Session just before posting
this message. I have been getting this error for a while now on number
of computers and was not able to fix it. I cannot debug this neither
because the error occurs on some of the clients computers. I was not
able to replicate it on my computer so far. Bottom line without try,
catch, finally, disposing, or destroying any object the POS
occasionally closes down my program.
Regards
