Re: 5250 emulation locks up on XP

Jim,

I haven't seen anything like this but other things I'd be trying to isolate
the problem:

Does it always happen with the same app or different apps?  Or maybe it
always happens on the same screen?  (If lockup occurs with different
applications or screens then you can likely rule out the application as the
problem).

Could you replicate the problem by just holding down a key on the keyboard?
(maybe it's a certain sequence of keys causing the problem)

Does it happen when the users type too far ahead? (could be filling up the
type ahead buffer)

Maybe the buffer problem is in Windows XP.  It didn't happen on Windows
2000?  Could you install Windows XP on some of the old hardware and see if
you get the overflow problem with the old hardware but with Windows XP?

Maybe it's a PC hardware problem.  Are all the new Windows XP machines the
same model?  Do you have a different model of PC running Windows XP that
also has the lockup?  Could you install Windows 2000 on the new hardware and
see if you get the lockup?

Also, have you taken a look at these applications to see if you can speed up
their interactive performance?  If they are doing a lot of updates that take
awhile maybe throw some data in a data queue and let a batch program do the
updates.  Maybe the screen I/O could be tweaked with some changes to the
display file and the way the program formats the screen.
