something strange going on here. i have tried wexist and wvisible and both are now working - however - it does not tell me if the operator manually closed the window. the sytem hangs if the window is not closed manually. (even theough the window is closed by the program). is there a way to tell if the operator has clicked on the X or perhaps force the click on X.
