You mentioned that pressing the button would return a 27 which looks like an ESC key to me. But I believe I also SET ESCAPE OFF in the form Load procedure. Any ideas why it's not working to break out of the loop? That's all that is wrong with my form. Here's my code:

>DO WHILE .T.
> SCAN
> DOEVENTS()
> IF LASTKEY() = 27
> EXIT
> ENDIF

> ENDSCAN

You need TWO exits - one from the SCAN, and one from the DO WHILE, or you need a way to terminate the DO WHILE, like:

lExit = .F.
DO WHILE ! lExit
   GO TOP
   SCAN WHILE ! lExit
      * do what you want
      DOEVENTS()
      lExit = (LASTKEY() = 27)
   ENDSCAN
ENDDO
