E9.2 CafeOne freezes when using custom attachment application


Hi all, we're having a trouble with the CafeOne resource. I made an application to search the attachment of a row (data passes by form interconnection) and we use it in a CafeOne, it works actually, searches and shows the media object panel but when the user wants to close the CafeOne or click the "minimize content" button, it freezes and user can't close it. If you press Cancel button of the application, it shows "Synchronizing..." window unkillable. It's not happening before showing the Media Object panel (there are some fields to set the Media Object function and a "search" button that executes it), just after the search and the Media Object panel shows.

Any idea with the behavior between CafeOne and Media Object panel that causes this?
