Hank: You are DEAD ON. I had a timer button on every form where the problem was occurring. Disabling it solved the problem immediately.

Thanks a ton to you and to everybody else out there that participated. I NEVER would have solved this one by myself. You gotta love UniversalThread and all the great people out there who are willing to help. If any of y'all ever get down to St. Croix . . . .

John

>>I have, by now , written several programs in VFP and used a lot of combo boxes. All of a sudden, in my latest venture, none of them are working properly. Here are the symptoms: If I run a form, press the Edit button, and go straight to the combo box, it will not "keep" any selection I make from the drop-down box (the Style property is 2--Drop Down List). If, however, I poke around on the form and go back to the combo box, it functions just fine. Or, if I type the first letter of the desired choice, it works fine (sometimes). I just cannot select from the drop-down box. Instead, the combo box remains empty and, if there happens to be a control "underneath" the selection that I click on, focus is shifted to that control. It is as if the drop-down list doesn't exist. This behavior happens whether I use my sub-classed control or whether I use the VFP standard control with no custom methods at all. It also happens , irrespective of how I fill the combo box.
