I've installed @tomic's mod and think I followed all of the instructions, although I was a bit concerned that the line number references were a little off (255 instead of 277 in inc_header.asp, 76 instead of 79 in inc_header_short, 42 instead of 46 in inc_iconfiles.asp).
I've added a test post, but I don't see any changes or any way to spell check a post.
I'm sure that this a ID 10 T problem, but any help would be appreciated.
