C# Context Menu not getting destroyed

[qwikstix]

I have a right click menu on my page and when I right click but click away instead of choosing an option, I get very weird behavior on the rest of the page. The text input controls are unable to receive focus. It appears that the right click menu is retaining focus even though it has disappeared. Even though I can't see the right click menu, navigating up/down with the keyboard arrows and pressing enter executes options on the now-invisible right click menu.

I've tried explicitly calling .Focus(), .Select(), .BringToFront(), etc. on the text controls to bring them back into focus after I've clicked away from the right click menu, but nothing seems to work.

Calling .Dispose() on the right click menu's _Closed event throws a fatal exception. The only solution I can find is to SendKey an ESC key to mimic the user destroying the right click menu that way but that seems risky.

Any ideas?

Is this a web application by any chance? Since they don't normally support custom right-click context menus, it's all funny javascript.

If this is a windows application, are you doing anything funky with the context menu, like calling it manually (instead of just assigning it to a control) or anything?
