What OS are you using? Can you find out which process is taking up most of the CPU? On Windows use the Processes tab of Task Manager, and click on the top of the CPU column to sort by CPU usage. On Unix use the "top" command. This may give helpful clues...

OK, so that means you've got Windows Task Manager, right? Which process is taking up all the CPU? Is it even a java process?

smartHawk, we find that the Ranch is a more pleasant place when people don't use obviously fictitious names. Please review the JavaRanch Naming Policy and change your display name to comply with the guidelines. Thanks!
