It's generally dangerous to do things like that because you don't know which database you're retrieving resources from. IIRC if you call DmOpenDatabase explicitly on your database first it might be okay, but I think the safer trick is to call SysAppLaunch on yourself and then do whatever you want in your PilotMain routine. Presumably on OS 5 you're handling notifications via launch codes anyway. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
