As Nadya posted, you can use Ed Rauh's approach with CreateEvent or you can download George Tasker's utility from the Downloads section (http://www.levelextreme.com/wconnect/wc.dll?UniversalThread~2,54,Forum=5,28,471) or you can read his article in FPA from November 1998 (it used to be available on-line but not anymore).

HTH.
