Extreme swing app instability under JRE 1.4.x

In upgrading to Weblogic 8.1 I've had to also port my code from JRE
1.3 to 1.4. I've had no problems with our application server EJBs and
servlets. However I'm having a great deal of problems with many of our
Swing applications and one in particular.

On client PCs (Win 2K), while being used, the application hangs at
completely random points of interaction. I've tried to establish a
pattern but there is none I can detect. The problem is easy to
reproduce. But it is not predictable. You may click on a tab or select
a row on a table for instance and it will just sit there unresponsive.
No CPU cycles used, no interaction with app server. Nothing.

I've followed the advice of other newsgroup postings and the sun bug
database (#4713003):
-upgraded video card drivers
-upgraded directX
-tried the -Dsun.java2d.noddraw=true and -Dsun.java2d.d3d=false
switches

All to no effect. The only real progress I've made is moving from
1.4.1_03 to 1.4.2_01 when it was released. The app is much more stable
under 1.4.2 but still basically unusuable since it still just freezes
regularly.

I've also tried the client on different types of hardware. New Compaq
laptop (ATI Mobility Radeon 7500 card) and new Compaq desktop as well
as old Gateway desktop (ATI Rage 128 card). The client is orders of
magnitude more stable on the old Gateway as compared to the new
machines. Freezes occur but are much fewer and far between.

Would appreciate any and all helpful suggestions as to a work-around
or resolution.

Thanks,
