I cannot use mouse to copy highlighted texts in the editable field (Reply box, Signature edit, etc) in Firefox.
I get this message "Your browser security settings don't permit the editor to automatically execute copying operations. Please use the keyboard for that (Ctrl/Cmd+C)."
Have not tried IE yet.
 
oh yeah, after paste into the field, I lose the blinking text cursor as well, until I click on some other part of the browser window (such as URL) and then come back.

Same here, for cut, copy and paste.

I have the same problem, clicking "source" within the text editor changes the editor mode and it seemed to help out which can also be changed in preferences from the looks of it.  If it does help, it's only a work-around.  Any suggestions?
 
Win XP-32
Firefox 4.0.1 (Give me back my 'back button' cascade menu.)

Try switching to the BB code editor instead of the rich text editor.
