Application Error When Unloading form

Hi

I have a form with an activex on it in aprogram that starts from Sub main and when I call unload form (from sub main)I receive an application error:

The instruction at "..." refrenced memory at "...".
the memory could not be read

I dont need the form really and I use it only as the container of my ActiveX control

could someone tell me What is the reason?

Thanks Ehsan

You sure your activex on form is not running some code? You sure you have only one instance of form (or only the form) loaded?

Special thanks to Lothar "the Great" Haensler. Come back soon, you Guru.
