Disable double-click pane caption for docking

In the program that I have created, when a pane's caption is double-clicked, the whole program crashes.  Is there a way to disable double clicking the caption to automatically dock a pane?

The program is very complex that I am creating.  There is really no way to post a code sample. 

When you double-click the pane caption, several Action events are run.  In those events, I create and destroy other windows.  When you manually drag the pane, there is no problem.  When you double click the caption, there is a crash.  The list of action events is basically the same for each way.

I found a way to prevent the crash.  In the Action event for the docking pane manager, instead of immediately destroying any pane, I start a timer.  After 100 milliseconds, I destroy the panes.  It seems to be working.

My preference would have been to disable the ability to double click the Pane caption.  I don't like it automatically docking.  I think a better approach would be to run an event when it is pane caption is double clicked and let the develop decide what should happen.
