Can someone explain me this.

I have PUBLIC variable oApp which is Application class and in oApp there is collection of forms oApp.Forms in which I add objects of my form classes.
In Application class there is method do() with READ EVENTS command.
Every time when I try to add form in collection oApp.Forms and to show() it VFP crashes and it brings on Fatal Error message with Exception Code = C00000005 indicating that there was an error in line in method do() where READ EVENTS command is.
This happens every second time.

Can someone help me about this?
