Desktop sharing applet does not stop in IE 11

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Confirmed on both demo.bigbluebutton.org and new server just built.
2. IE11, cleared cache as well.
3. Start meeting in IE11,  start deskshare either region or fullscreen
4. Deskshare works fine as expected.
5. However after hitting CLOSE on deskshare, then the ALLOW on script warning, 
another instance of applet starts.  You can hit start to stream but wont show.  
No way to get rid of applet except for meeting close.

What is the expected output? What do you see instead?

New applet should not start again.  

Not sure if new published stream on 2nd attempt might show in recordings.

Confirmed the problem with IE.  The applet launches again.  The good part is it 
doesn't properly broadcast on the second launch, so the presenter isn't sharing 
their desktop unaware.

Thanks for pointing this out Steve.  We'll start working on it.

trying to trouble shoot.  question in addition to deskshare.js change, the 
applet was modified to support new java as well? i believe.

I was looking to try to find all the changes, i see under v0.81-release the 
deskshare.js change but no changes to applet.  Is this under different tag.
Should the applet have a new revision number for jar?

Hi,

Could you try it again on 

  http://demo.bigbluebutton.org/

We've changed how the applet stops desktop sharing, so it might bypass this 
issue with IE.

Cleared IE cache and made sure no java cache,  the problem still exists on 
demo.bigbluebutton.org IE 11
