Trying to revoke a drop target that has not been registered with TWebBrowser.

Attempted to use this code within D7 under a custome class. If the tWebBrowser is made on a form at design time, the code works. If its made at run time, it does not want to work. It enters an infinite loop. Checking with the query, it always appears to return 0 (Zero) with a run time created web component.

Trying to revoke a drop target that has not been registered with TWebBrowser.

Also keep in mind that during the Application.ProcessMessages loop, it's possible to free the object which you had just begun requesting to Exec something (happened to me in an MDI app). The result is, of course, an Access Violation.
