I left my Linux GUI on over night (Idle for about six hours) and it was fine this morning. Other than some cosmetic issues this release has mostly been flawless.
Only Issue: Sometimes the title bar menus (File Account) disappear and I can't exit the client. I've tried stop, exit, etc. from the console but they do not work. When I go out to a shell and kill the process it reports a seg fault. I'll see if I can reproduce running in gdb.
