I have created a Project in Visual Foxpro 6.0 with several forms & prgs. When I was almost at the end of it, I am beginning to have following errors.

1.Some of the forms have 'OK' Button to which 'Thisform.release' is attached followed by 'do form' command for next form. The button was working fine. But suddenly I see that when I click the button, the form does not close but the next form opens up. Why is this happening ?
2. After Instantiating such troublesome forms, If I try to close VFP, an error message comes 'Cannot quit Visual Foxpro'. Then the only way out is to end task through Windows 'Close Program' window.

Can any body help me on this ?
