Opening PM's - a mod to make it better?

[flying dog]

Ian,

 

When I get a PM, I am asked if I want to read it, then an option (well two choices) 1 - open in THIS window or not.

 

Alas the OR NOT option opens it in a new window.

 

I'm using Firefox - and usually open new tabs; not windows.

 

Could you make it a 3 way choice: 1 - this window 2 - new tab - 3 - new window.
