RCW Error

[haseebhm]

Hello. I am using a bound MSHFLEXGRID Control on a form. When I click the "CLOSE" button, it works fine and the form closes. But when I press ESC or ALT+C, I get the following error.

 

An attempt has been made to free an RCW that is in use. The RCW is in use on the active thread or another thread. Attempting to free an in-use RCW can cause corruption or data loss.

 

Please Help
