Our application is winforms userControl which is invoked within VB6 using a interop, this works perfectly fine. However with that said, there is a senrio where the system throws a RT.
Step1: Open a form with wingrid that has data and open grid filter,
Step 2: Close the form, without collapsing the filter dropdown. Even though the form is closed some kind of object remains on the MDI
Step 3: Open another form and click on any kind of drop down. The system blows with the below exception.
See the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box.

This problem occured for us up to 12.1, but not in 13.1.
In 13.1 the combo seems to get closed when it loses the focus better.
