if you have a fast interval under 5000 (5 seconds) I have seen soom very funny stuff
If you are trying to get a up to the second reaction from the timer then you are asking a lot from VFP

>In certain circumstances, it takes multiple attempts to click buttons on the forms before the button actually registers the click.

>HOWEVER, by clicking both the LEFT and RIGHT buttons on the mouse at-the-same-time, yields 100% success rate every time! Strange!

>Upon further testing, the RIGHT mouse button always seems to select the button properly, while the LEFT mouse button clicks it and gets the button to work.

>So I figure that the RIGHT button is the key instrument to getting this 100% button-clicking success rate.

>Any ideas why? Or how I can get the LEFT button to work 100% like the RIGHT button? I was thinking that maybe I could force a RIGHT-mouse-click everytime the user clicks the LEFT-mouse button. Any ideas if this is possible?

>Anyone else have encounters like this?
>Thanks for any help!
