Hi List, I just wanted to give you all a heads up in case you ever work with 
Oracle Forms (I think this may apply for Oracle Apps/EBS too) that if you have 
users that frequently have problems with the forms freezing up on them, it may 
be an issue with Java running on dual-core CPUs.  I've been struggling with 
this for months and tried several different versions of Java, IE and even 
Firefox along with everything else we could think of and in multiple cases, the 
only solution I've found is either disabling one of the CPU cores, or 
(preferably) setting processor affinity for the java.exe process.  You can do 
this temporarily through the Windows Task Manager, or you can make it 
persistent by downloading the imagecfg program from the link below and running 
it like this:

imagecfg.exe -a 0x1 "C:\Program Files\Java\jre6\bin\java.exe"

I also found a few other users experiencing the same issue and an Oracle 
employee confirming it in the Oracle forums here:

Note that the Oracle rep suggests running the latest versions of Forms, IE and 
Java as a possible solution, however I tried that and it didn't help.

Hopefully this will help someone else avoid the months of frustration I've had 
with this problem.
