I am using SQL Developer version 3.2.09 on Mac OS 10.6.8. Whenever I leave the app open for a little while to do something else and come back to it, any action I try just locks it up. I can't even quit the app without doing a Force Quit. If I disconnect from all of my database connections first, this won't happen but I like having the app open and ready to go during the day when I need it. Any suggestions?
