Thank you Sergey
I have several ways to correct the problem by changing the call to wexist.
But I have too many wexists scattered by the code.
I think will change the _screen's caption by putting a dot or something before the user's text.


>That makes WEXIST() function totally unreliable. Take a look at _WFindTitl function in FoxTools.

_screen.caption = "Hello - mYapp"
>SET LIBRARY TO (HOME() + "FoxTools")

>? _WFindTitl"Hello")
