I have a VB6 application with a lot of controls (sometimes even reaching the maximum set by VB6 for a form, we then create custom control to bypass this limit). On some PC, some buttons/combobox/checkbox disappear. They appear when you click where they actually are and still fire the events, but until the click you're just not able to see it. It's just 1 or 2 controls of the form, everything else is behaving like it should.
It appears on some PC, not all, and the "hidden" controls are not the same from PC to PC (and the majority of the PC the soft runs on have no problem at all). The Visible property is of course set to true. I can't even reproduce the problem at will...
Do you have any idea of what can cause that? Thank you.
