How do you mean 'exactly'. What I observed with Viv's code is that the timer's Timer event did not even fire *once* during the loop! It is my hunch that the intended behavior of vfp is that the timer is not actively visited during execution of consequtive inputless commands. You suggest that this intention is not guaranteed everywhere/everytime. Can you write a program that gives support to your hunch?
