I am runnig windows 7 ulimate with a dual monitor setup.

When I was running vista I could open for a example a youtube window on my second and i could run it ful screen and use apps on my first monitor.

Now when I put a window full screen on my second window and click on my first screen the window on the second monitor goes to it's normal size which is annoying.

Anyone know how to fix this...
 
The problem is to do with which monitor is set to your primary monitor.
Just switch it in the settings.

You can easily drag the taskbar to whichever screen you wish even if it is not the primary monitor.

The "problem" is actually to do with Flash. It won't allow it to be run fullscreen in a window that isn't the main focus, ie your secondary monitor when the focus is the primary.

This is intentional as a Flash security feature. It can however be hacked. Which browser do you use for a start?

You need to hex edit your flash.dll and then it will allow you to have full screen videos in your secondary monitor. You need to backup your flash.dll, and then hex edit it, so that you can run it full screen. Even if the other monitor is set to the primary, it won't affect Flash, as it can only run full screen in the monitor that is the main focus at the time.
 
The hex editor hack works but it depends on the browser you use.
Won't work on IE or Chrome.
If you use firefox or Opera you just need to navigate to..
C:\Windows\system32\Macromed\Flash\ or C:\Windows\SysWOW64\Macromed\Flash\ folder on Windows 7 64-bit
Search the DLL file in a Hex Editor for the following string
74 39 83 E8 07 74 11 83 E8 05 75 13 8B
and change the first two hex digits to
90 90 83 E8 07 74 11 83 E8 05 75 13 8B

Make sure you make a backup of your .dll 1st tho. just to be safe.

Edit:
For using this with Chrome (as Chrome comes with the Flash plugin) open
C:\Users\username\AppData\Local\Google\Chrome\Application\6.0.427.0\gcswf32.dll

Keep in mind that Adobe claim the reason why flash doesnt stay in fullscreen on duel monitors is "for security" so doing this is at your own risk. It does suck that Adobe can't release a flash plugin that allows us to keep fullscreen on an a monitor whilst using another.
