I haven't seen before.
I start my debug session with a config-code.fpw. screen=off Resource=off Safety=off Title=KIOSK11-CODE Command=Do ..\pckiosk11.resource\StartUp-Code.prg
The StartUp-Code sets a few extra things, opens the debug window and starts the code DEBUG
SET ASSERTS ON SET PATH TO SET CENTURY ON
DO checkin.prg ON SHUTDOWN QUIT
I have a "SET STEP ON" in my code to step through a bit of code. Well, I am unable to step through the code. Resume fails as well. The Cancel button works. When I close the Debugger the _Screen appears. Oh, this is an app that the ShowWindow is set to 2 - As Top-Level Form.
Once the Screen appears, I need to type ON SHUTDOWN in the Command window to be able to quit.
As I typed all this out. I continued to think of things I should try.
So I added a _Screen.Show() just before the DEBUG and I'm able to Resume and stop through my code now.
Hope this helps someone in the future.
Have fun, see you at Virtual Fox Fest 2022 soon! Tracy
