Since we've moved to the new version of SMF, I have been unable to use the Alt+S shortcut. Actually, I can use it if the page still happens to be loading, but not if it's already loaded up. For example, I can type my comment then hit Alt+S with no luck. This also blocks the "Post" button so I have to refresh the page before I can post. While the page is partially loaded, I can hit Alt+S and it will post but if I let it load up and wait a little bit, the above behavior occurs.
At first, I thought this was due to the latest Firefox I had installed but I'm able to use the Alt+S shortcut in the Dem fora, as well as others that I've tried recently so it's just this fora. I don't know if it some module added to the install or what but I was just curious as to whether anyone else has this problem.
