Thanks for posting this exception.

Replacing the document while the combobox control is going to drop down? 
That's like freeing a form in the dropdown event handler, which is raising 
exceptions as well.

The object click handler should send a message to your form, which will be 
processed after dropping down.

The only thing I could eventually do is to prevent the object click handler 
from removing the current document.
