Can't close main form!!

[richiemac]

Hi all, I've created a form with a number of child windows. One certain window is behaving very strangely. If I open the child window and then close it, the main form will not close - by this I mean I can't click the exit button or use the exit menu item. The main reason for my confusion is that this behaviour only happens on certain machines. Does anyone have any knowledge of why this might be occurring? It must have something to do with the individual machines but I can't find anything that would cause this and I was just wondering if any of you guys have come across this before. Thanks in advance Rich

I think there is a problem in your code. Try to debug, after you close certan window. Or try recreate this child window. quote: behaviour only happens on certain machines If you use same setting for this child window then all child would have same problem

That's what's confusing me. If it happened everywhere I would at least have a starting point.:confused::confused::confused:

Try to disable all your code. If error still exist, try to delete and create another child
