When working with dual monitors I’ll often watch online programs.  Normally when I have the progra fullscreen and then click anywhere else on the other monitor it will break the fullscreen mode.

UPDATE 11/19/10: The below no longer works 🙁  Though, luckily there’s a newer and much easier way to solve the problem!   Just download and run Ignoflash find “gcswf32.dll” and hit apply, easy peasy 🙂  At this time you can find the latest version of the ddl for chrome on Vista here:

C:\Users\{user}\AppData\Local\Google\Chrome\Application\7.0.517.44\gcswf32.dll

Like before you may need to turn on “organize>folder search and options>view>show hidden files and folders” to find the file

.

It can be really annoying so I took a look around the internet and found this:

All you need to do it place the NPSWF32.dll file here (for vista, and make sure to backup the original file!):

C:\Windows\SysWOW64\Macromed\Flash\

For chrome you’ll also need to make some changes to file  as outlined here:

Then copy the file here:

C:\Users\{your user name}\AppData\Local\Google\Chrome\Application\6.0.408.1\gcswf32.dll

and you may need to turn on “organize>folder search and options>view>show hidden files and folders”

And you’ll have fullscreen awesomeness no matter where you click 🙂
