You could do a 'FindWindow' on you own title bar. So you run, change your own app title to 'I am a Wombat' or something. Then do a FindWindow for 'WhizzyGame'. If you find it, then you are already running and will exit.

Otherwise, set your apptitle to 'WhizzyGame' and continue.

I think this is the FindWindowAPI call...

.lib "user32.dll"
 
FindWindow%( class$,Text$ ):"FindWindowA"
