SQL Developer keeps locking up when I copy/paste text in a worksheet. It happens when I past into SQL Developer from itself or from another application and also when I past from Developer into another app. Sometimes it locks up when I hit Ctrl+c (without yet hitting Ctrl+v.) When it's locked Developer is completely unresponsive. It will not Close and has to be Terminated. Google is unhelpful... Is this a known issue and how can I fix?
Windows XP, SQL Developer 184.108.40.206.67
