Hey robinski and welcome to the city where we've worked hard over the years to avoid a descent in chaos.
The problem with that code seems to be present only in the Insufferable Encumbrance. I found a couple of documents that discuss this issue (the top two returns in this search), but they didn't help mme much.
As a hack coder, I'd suggest something like this:
<FONT color= Navy size="4" valign="middle" height="100"> <MARQUEE bgcolor= "#FFFFCC" direction="left" loop="20" width="100%" height="25" SCROLLAMOUNT=3>......MESSAGE </MARQUEE>
