UPDATE: These instructions only work on older versions (10.0.22.87) of the Flash Player – there is an updated, easier solution here (via Lifehacker).
If you have two monitors like I do, you may like to have full-screen flash videos playing in your second monitor. There is a problem, though, that as soon as you click in a different window, the Flash goes to non-full screen. In other words, you can’t browse and have full screen flash on your second monitor.
There is a fix for this “security feature,” though. (Disclaimer: Adobe claims that this feature of auto-minimizing is integral to computer security, so proceed with caution)
- Make sure you have Flash player version 10.0.22.87 (you can see this version information here).
- Open NPSWF32.dll (probably located at c:\Windows\system32\Macromed\flash\npswf32.dll) in a hex editor.
- Go to address 0×136340 and change byte 74 to EB.
I have tried this, and it works great. Original source here.

Works great. Thanks.
Shouuld mention that in Windows Vista npswf32.dll is located in windows\sysWOW64\macromed\flash

Thank you so much for this! I have been trying to figure this out forever now!
Thanks, this worked for me.
Not sure what security feature this would be for… frankly, i don’t care.
If it requires a manual hex edit to trigger this security lapse, I’m sure that it is not a wide attack in the wild.
That is awesome.
I was suffering from this feature for some time. I have a 22″ LCD that I work on normally, and for watching films I have a 42″ Toshiba screen.
You have just made my day
Thanks

Thank you so much, this has been driving me crazy for years. I live in China so I watch all my TV streaming from the web.

Nice tip, thank you!
When I tried it, it said: Cannot open file …. for write access. Access is denied. Does anyone know how to get around this?
Hmm I finally was able to change the file, but it didn’t change anything…when I am gaming, and I try to watch anime on my second monitor using Veoh, it still minimizes one of them.
Jei, please try the updated link here: http://my.opera.com/d.i.z./blog/2009/04/22/watch-fullscreen-flash-while-working-on-another-screen
I hope that helps.
I love this hack. Have been searching for a way to do it for a while.
Created the following tool which will perform the ‘hack’ for you. No hex editor needed.
Enjoy!

Source code can be found here:

I will also open a dedicated forum for the patch, but for now you can report problems in the general section of the forum or via email.
Thanks Jmaxxz, that works well! – http://jmaxxz.com/index.php?option=com_content&view=article&id=89:flashhacker&catid=16:downloads&Itemid=32
A solution with no hack and that works with any version of flash and different web browser : flash-full-screen-multiple-monitor.clangen.com
Just download and install “Flash Keep FullScreen” !
It’s the easiest way I found, and it works.
