Steps to Reproduce Behavior

Paste the following code in a program (.prg) file named Test, and then run the program from the Command window:

NOTE: The code creates and runs an .exe file, that runs a form. The .exe file then tries to delete the form file.

SET SAFETY OFF

*  Using VFP6 compatible code:
set print to myexe.prg
set print on

\	myform = "testform1"
\	DO FORM (myform)
\	CLEAR ALL
\	CLOSE ALL
\	RELEASE ALL
\	CLEAR ALL
\	CLOSE ALL
\	myform = "testform1"
\	ERASE (myform + ".*")
	
set print off
set print to

clear typeahead
KEYBOARD "{ctrl+W}"
CREATE FORM testform1

BUILD PROJECT myexe FROM myexe
BUILD EXE myexe FROM myexe
RUN /n myexe

Because the .exe file has not released the form file, you receive the error message that is described in the "Symptoms" section.
