Grigore,
Have you checked the property setting while the form is running? This is the classic indication of the problem.
Do you have any ActiveX controls on the form? Objects over the top or each other.
>David, I am positive this is out of the question. Categoric. They are not drawn on the form, but they are still there. If I click in one of them, it becames visible and I can use it. After clicking another, the first one dissapear.
