Chris -
Well you learn something new everyday (hopefully). SET COVERAGE is a new one for me. It revealed (at least it appears ) that the mainform is being refreshed during the report run. There is a control on the form that resets focus to the TIP cursor when it is refreshed. Hence, there is the problem. Whoda guessed? But when I cleaned up the code to leave the cursor where it started, the problem was solved.
Thanks!
