Hi, Im having a random issue with osx snow leopard that its making me mad. When i go to lunch i usually block the computer with the "Login Window..." on the user menu (menu bar). This has always worked for me since Tiger, but with Snow Leopard after i login in again sometimes all applications that i left open are now closed. Apps, dashboard, everything, its almost like i've rebooted the machine. I know that it didn't reboot though. Firefox for instance, even not running in the dock, refuses to open saying that "only 1 instance can run at the time". I have to kill this process on the Activity Monitor for being able to open firefox again. My SnowLeopard was installed as a upgrade to 6month Leopard install. Sorry for the long description, has anyone experienced something similar?
