Don,
I use :
set reprocess to 1
But that doesn't explain the exit unless there is code to exit on escape (with automatic user would to press esc) - a button where 'cancel' property .T.?
You don't need to write code in DE.init nor change form.buffermode.

In DE, set buffermodeoverride for table(s) to 4 (and orders as well). (Just for it's easier - init coding would do too)
