Hi When I use either $MB_SERVICE_NOTIFICATION or $MB_DEFAULT_DESKTOP_ONLY flags (or the decimal/hex equivalents) for a msgbox, the timeout doesn't work. eg #include <MsgBoxConstants.au3> MsgBox($MB_SERVICE_NOTIFICATION, "Title", "Text",10) Does not time out.   I am running the latest public release ( and have tried the most recent Beta ( but no joy.   Has anyone come across this before? any work around?     Thanks   Rich
