Hi David

I have also discovered that the problem only seems to occur when the "Property Window" is open. The only items affected are Labels, Shapes and command buttons. All other controls display properly.

>>I had an opportunity to test two forms with 10 controls on each form as you suggested and everything worked correctly. So I proceeded to create a toolbar with two graphical check boxes that simply issued loFormA.Show or loFormB.Show when clicked. I clicked the check boxes may times and I never experienced a problem. Then I ran the application where I had the problem the day before. No matter how many times I clicked the toolbar buttons I could not make the forms display incorrectly. Yet the previous day I would have an incorrectly displayed form after two or three clicks on the toolbar buttons.
