When focusing (clicking) a FLASH OBJECT (youtube player play button demonstrates this) the F11 key stops working to set full-screen (even with no listeners dedicated to this key in flash)

When in a site with no-scale flash object set ( this causes main problems:

- The only way to exit FScreen is to open a new tab (with no flash focused) to regain F11 key control. If a dummie user does not know how to do this, he will have to ctrl-alt-del, maybe will even reset the computer.
- The tabs bar does not hides itself after hitted.

Other problems within Full Screen and Flash: the cache constructed by a session in the site within a while in full screen turn impossible to finish to download a new session of the same content after closing the first (

Reproducible: Always

Steps to Reproduce:
1. go to and select any movie page to open a player (ex:
2. hit play button on youtube player (set focus to the flash object)

3. go to or
4. enter full screen (if the stage area has been clicked F11 is already disabled).
5. mouse over the tabs bar

-> happens in large sites with streaming
6. wait some minutes on the site in full screen mode.
7. close the browser.
8. reopen and access the same site (

Actual Results:  
1-2. The F11 key does not map the Full Screen state change function.
3-5. The tab bar does not hides itself. The F11 key does not exits the full screen mode if the page was hitted.
6-8. The site loading will not finish.

Expected Results:  
1. The F11 key working to change screen states.
2. The tabs bar working on hidding and showing itself
3. The content finishing download

This bugs was tested with ADOBE FLASH 9
No theme used (windows 98 theme) no repsonse

can you reproduce this using FF 3.5 and flash v10?
Note: I think eating of some keystrokes when flash is focused is normal behavior
