I use both Firefox and IE7 - but I have to remember to use IE when submitting a Waymark. Otherwise, spurious characters are added at the end of the Long Description. This seems to have been happening for as long as I can remember - known bug? To clear the characters out (they are invisible in Edit mode, but visible when viewing the Waymark page), I have to edit the Waymark using IE7 - any dummy edit seems to do the trick.
