ExitInstance Problem

Good day everybody...

I just wish to know, why do my application does not go to the ExitInstance function when I quit the application?
As a result, I have memory leak on my program as I can't release the memory through that function.

Thanks in advanced.

Well, do you need me to give any information that would help you in helping me?

But, basically, it's just a normal MDI application. The forms used are only for data entering and searching. You know, those normal 'procedures'.

thanks.
