Karen, here is a better sample that I clipped from one of my DBGrids.

I'm interested in hearing how you used a form timer to do this. At one client I have a nice DBGrid with an on click EEP that brings up the individual edit form. The eep closes the form completely, then brings up the individual edit form. My problem: everything is run from a main menu that stays in the background. If they double-click on the DBGrid row rather than single-click, it actually launches the first item on the background main menu as if they clicked on it! This happens in the second it takes for the individual edit form to come up! So they end up with actually 2 forms on their screen (and they aren't MDI forms) so that confuses RBase and it locks up. I was thinking I would either have to replace the DBGrids with list views so they can double-click, or perhaps close that main menu and have all forms come off my main app instead. So how does a form timer help that? Karen About a year ago I struggled with a similar problem. In my case, I isolated the problem to forms with DBGrids where I make use of the on click EEP. I discovered that some users would click multiple times (instead of once) causing various errors or erroneous results (including occasional access violations). To resolve the problem, I made use of the form timer to restrict the clicks to one. If your problem is similar to the problem I had, let me know and I will send you a copy of the code that I use. I am not in my office at the moment but I should be back around 2:00 PM and I will send it to you if you want to give it a try. John
