Browser window management

Hey all,

I thought this would be right place to ask this. Here's the thing:

Let's say im watching Flash video with fullscreen ON (Youtube, justin.tv etc.)

Is it possible to have another window on top of the fullscreen flash? Let's say i want a small pop-up chat window to stay in screen so i can follow it. How can get the window to show? In windows it's just like alt+tab the window but it's not working.

I'm using Google Chrome as my browser.

cheers

Incase this sounds confusing..

What i mean is:

I don't know if it's called like "floating window on top" or something. Should be SIMPLE....all i want is to have another window ON TOP of my fullscreen flash video.

It's really simple in windows, just alt+tab the right window to the top and u can see it. I cannot acces or tab ANYTHING when im watching fullscreen flash video and it's really annoying.

EDIT: Also im using OS X LION 10.7

 

I am not trying to break the bump rule but im getting a little frustraded for sure. Sorry!

Found this by googling:

Not sure yet if it works in Lion and it really does seem a bit clumsy. Is it REALLY possible that 3rd party software is needed to achieve this really simple task? All i want is a small browser window to stay on TOP. It could already be implented and i am stupid, that's fine but i wanna hear it now!

Also, how is this not discussed more. Cannot seem to find alot of discussion about it..

Someone might ask that why you want this? Well, let's say i have only 1 screen = i am using my Macbook Pro. Do i really have to exit the fullscreen flash video and use mission control or switch to the other window manually everytime TO SEE IT?
