Lawson AR and PO screens freezing up

Platform/version you are on?
Can you check ladb.log in your LAWDIR\System for error?
Is the behavior occuring in both PORTAL and LID?
have your network guy check for any latency in your network?

Lawson Insight 7.2.2, HP-UX, Windows Client/XP Pro
There are no errors in ladb.log.
We now have someone looking at WireShark captures on the network.
Thanks,
John

How long has this been happening? Have you restarted lawson and see if the issue happens over time or always?

Its been happening intermittently/ocassionally for several months, but has gotten worse the past 1-2 months to the point that the users have a very hard time during the monthly closing cycle.
Our Unix Admin has checked the system and found no problems . No memory errors. The utilization of memory, cpu and disk is fine. Disk space available is also good. No jobs backed up.
We have rebooted twice on a Sunday, and the users started complaiing Monday morning already.

And it happens in both LID and portal?

The problem only occurs on the LID (just verified with the users).

Can you post your UNIVWIN.ini? Also, how many users do you have?

If its the same as univ.cfg, then this is it. We have 288 active accounts, with a peak of about 50-60 during monthly closing. There are 23 users on the system right now.

do you see any error in your latm.log?

We don't use latm - had a lot of trouble with it, so it's been turned off for years. BUT it was turned on for one week recently to see if it would help with our screen freeze-ups, but it did not. I see no error messages in the latm.log during that period. Here's the latm.cfg file (only active during Feb 21 - Mar 3):
