Ultimately what I am trying to is create a public computer session manager.
1) User logs in and main application window is withdrawn (easy) 2) After (for example) 55 minutes - a warning window/dialoguebox "session will end in 5 minutes" 3) With 30 seconds to go - a warning window/dialoguebox "session will end in 30 seconds" 4) User logged out (easy) I am having problems with steps 2 and 3 Either the window/dialoguebox will (a) pause the program execution upon display waiting for user input or (b) both warnings display together when application has finished. What I want want is a window/dialogue box that will not halt application logic, and will display immediately. cheers David -- http://mail.python.org/mailman/listinfo/python-list
