Ebiz 12.0.4 Mouse stops selecting fields in Forms

Question

We have a real obscure issue, Oracle and our ASP is unable to help us. After upgrading from 11.5.9 to 12.0.4, we noticed the following issue.
After some time when a user is in EBIZ (most of the time happens in Support or OM responsibility) the form will stop taking clicks from the mouse, and you have to use your TAB key to navigate between fields. Clearing Java cache and IE cache doesn't seem to help.
Our ASP has done all the usual thigns, recompiled forms, check invalids, we upgraded clients to JRE 1.5.0.16, but no luck.
At one point, we thoguht that other Java enabled applications were interfering, so I set some key users up with their own Windows XP virtual machine. The virtual machine works for some time without issues, but then the issue starts again.
If users restart their machine, they can use it again for a few days and then it happens again.
Some users said it stopped happening, but then after a few weeks it happens again.
We noticed this also in the Concurrent Program submission application, and various users noticed it in Finance, OM, Service, etc.
Is there anything anyone can suggest from this list? Feel free to email me directly if you like. My email address is [email protected]

Thanks Hussein, our ASP came back with those same articles, however the issue as we explained it is not a focus issue, it is mouse disconnect issue, i.e. it is like you unplug your mouse from the computer and try to use it to select fields. Only the TAB buton works to move around fields.
We have been through all the notes on Metalink and patches for Forms and JRE Upgrades and the issues still exist.
Is there any other way of troubleshooting this by way of logs and tracing to determine what is happening?
