I just put in a check for the empty string and it's working good.

Thanks,

Michelle

>Not sure if this will help, but I found situations where the native WONTOP() function didn't work. E.g. it returns an empty string when you're in the command window, the view window or the document view. In situations like this I use the _WOnTop() function from FoxTools. You could try something like this:

>		MESSAGEBOX("Cannot find FoxTools.fll. Procedure canceled.", 16, PROGRAM(), 1000)
>		RETURN
>	ENDIF
>ENDIF

>ENDIF

>_WSelect(lnWhandle)

>RETURN
