I have found that when this occurs, if I post my response above the quoted item rather than below it, the space bar works.

Alright, I don't know how you guys come up with these workarounds but you inspired me. I found that you don't even have to type a word, but that if you just hit the Enter key to go to a new line the space bar is then active.Keith.......I use Chrome, too. I have the same space bar issue when I try to post after a Quote. I discovered if you type one word, then press the Enter key to go to the next line the space bar becomes active again. I'll type one word, press the Enter key to go to the next line and type my post, then go back and delete the word on the first line. Works like a champ.
