Detaching remote screen session while in local screen session?

[Martijn Ras]

Hello,

I've been through all documentation i could find on screen but have 
unable to figure out how to detach a remote screen session while in 
local screen session?

Say i execute the following commands:

1) xterm
2) screen (<- Let's call this one: A)
3) ssh address@hidden
4) screen (<- Let's call this one: B)
5) ...

Now i want to detach the screen called 'B', so i can later return to see 
the output and results of the command in step 5, or even close the ssh 
connection until then. As is found out the hard way, simply pressing C-a 
C-d detached the screen called 'A', just closing the xterm creates a 
mess that is even worse ...

Any suggestions would be appreciated.

Mazzel,

Martijn.
