ObjectDisposedException

Hi,
One of our QA people found a crash in the dock manager, it happens consistently in our program, but does not happen in your sample application. I will keep looking on my end, but here is the problem, in case you have an idea how to fix it.

1. Click the thumbtack to hide a tool window.
2. Put your mouse over the window to bring it back into view
3. Click on the thumbtack again to keep it in view
4. A ObjectDisposedException occurs with this message:
"Cannot access a disposed object named "AutoHideContainer"."

Here is the stack trace:

Any idea would be appreciated.
