Issues with web menu display

I've upgraded a couple of my Xymon servers this week (to make sure I
was seeing this issue on both) to 4.3.17.  Both installed from RPMs I
built, which have worked for many years.  After this upgrade, I'm
seeing some strangeness with the web menus.  I dont' see this on the
main Xymon page, but when I go to look at details of a test, I see the
menu showing up like the attached picture.  Both systems are 64bit
CentOS 5.

I looked at the source and see some stray code:

/acknowledge.sh">Acknowledge alert</a><span class="invis"> | </span>

(and one or two other times).

I looked around and don't seem to see to be able to find anywhere in a
text file that I could look to see if I could fix this.  Can anyone
give me a clue of where I should be looking to figure this out?

I've also attached the full html where you can see the stray lines.

Thanks!
