Hi George,
In the forums I have it configured to always force pasting as plain text, so if you are trying to paste html it will strip that out, but if you are pasting regular text it should not strip that out and does not in my tests. In fact I use Chrome all the time when using this site albeit I'm on a 64 bit machine. I will try it on a 32 machine tomorrow to see if its any different.
Letting users paste html is risky because they may post invalid fragments with missing closing tags that can make the page not validate or break layout.
Hope it helps,
Joe
