Plugins disable right-click context menu

I needed to enable the ability to input flash video into the WYSIWYG editor for a customer, so I searched and found a solution here: http://www.snippetmaster.com/forums/index.php?topic=1782.0

Code:

",
plugins : "flash",
extended_valid_elements : "

Adding the code above into the "Extended Valid Elements" area of the general admin control panel enables flash videos to be input without being stripped by the editor. Unfortunately, it also (somehow) disables the right-click context shortcut menu within the editor. Given I trained the customer to use the right-click menu, this is a major issue as they also need the ability to input flash.

So basically, I'm just hoping there's a work-around for this considering we're probably not getting a new version anytime soon.
