After testing some code on my machine, I had a user who got an error message that read:

Fatal error: Exception code = C0000005...

Additional lines on the error message helped me to identify the offending line of code. It was MODI WINDOW SCREEN which I have used since the Fox2X days to reset "properties" for the main FoxPro window.

I fixed the problem by substituting the following code.

WITH _SCREEN
.CLOSABLE = .T.
.CAPTION = "MicroSoft Visual FoxPro"
.ICON = ""
ENDWITH

I don't understand why I had a problem in the first place. More than once, I've had a problem that didn't seem to be a problem. In many of these cases, I've simply found another way to do the same thing and solved my "problem". That's what I did again here.
