LaVolpe,Thanks a lot !! I used your last suggestion "A complete fix for the bug", no bug anymore ! I am impressed again by your high caliber in programming ... I agree with you that it's a bug somehow from VB6 , I don't know how to report it to microsoft, but anyway they don't care anymore cuz they stopped the support of VB6.
Out of subject,but want to mention that the button (browse), I made it based on your suggestions (hope i succeeded ), it's largely nicer than default vb buttons !! I will post later on when i get time in bank code the code for that in a project, so that if someone else a day has same question about buttons he will be able to check it
