@MGblues - thanks for reporting this. quick reply works ok for me in FireFox on XP, but I do see some other weirdness with the new editor. One plus of the new editor is that it does an auto-save every so often if you are typing a long post.
Try doing a hard-refresh in your browser: hold down the 'Ctrl' key and press the 'F5' key.
Firefox and Windows Vista.
It works fine now. I just checked and noticed I was still on Firefox ver 8.0. upgraded to ver 9.0 and now everything works like it should. It was probably just a glitch with me.
