Warp Fixpack 17 or later (including Warp 4) Hint

When using Warp Fixpack 17 and your desktop hangs, try pressing Ctrl-ESC to bring up the standard "xxx is not responding to system messages. Would you like to terminate it?" message. Then press Ctrl-Alt-Del to activate the Ctrl-Alt-Del Commander. This will pull attention away from a run-away program but still let you cancel it even though Ctrl-ESC cannot.
