I am testing a Java JFC client server application which runs on Linux platform The script runs fine with a single bean on 1 linux machine). The same script when it is run simultaneoulsy on multiple linux machines by using threads, an exception "<xxx> button not exposed" is thrown. Has anyone faced such an issue and resolved it. Please respond at the earliest.

Also, sometimes when I run a script it is failing at the Exists method on the main window. The same script would have run fine at an earlier date. Any reason for such behavior?

Thank you,
