MessageBox

While I agree that would be more convenient, AppTitle currently does the job:

AppTitle = "Messagebox Title"
Notify "This is my message"

So you could use something like:

AppTitle = "App Title"
Notify2 "Test message", "Test Title"
Print AppTitle ' verify that it was preserved

Function Notify2( text$, title$ = "", serious% = False )
	Local saved$ = AppTitle
	AppTitle = title
	Notify text, serious
	AppTitle = saved
End Function
