>no. the window flares briefly and then the wait wind message comes up.

You mentioned nothing about a wait window. If I Put this code in the EditBox.Click, it works for me:

LOCAL cOldSafety
cOldSafety = SET("SAFETY")
SET SAFETY OFF
STRTOFILE(this.Value,"xyz.txt")
MODIFY FILE xyz.txt
this.Value = FILETOSTR("xyz.txt")
SET SAFETY &cOldSafety
