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:Windowssystem32Macromedflashnpswf32.dll) in a hex editor.
- Go to address 0x136340 and change byte 74 to EB.
I have tried this, and it works great. Original source here.
