In this puzzle each empty square needs to be filled in with a different positive integer 1 to 40.

The rules are the same as the first sequence fill in and are:
Each string of adjacent squares needs to form an arithmetic sequence.
A horizontal string of squares increases from left to right.
A vertical string of squares increases from top to bottom.

Frankly I haven't seen this problem before, at least, I did see an occasion where one row of a grid may have stalled, but I put that down to my browser, therefore when this problem was discussed I had didn't truly understand.

I have Firefox and IE 5.5 on my computer; IE 5.5 opened in the same fashion as Firefox with seemingly no problem.  That said I checked with a laptop which runs IE 6.0.2*** [whatever].  Yes, the home page opened pretty much as one would expect except that the problem text was not there.

About the only difference between this and all others using XHTML is that this uses an HR line.  That would seem to be a logical explanation as the text disappears above that line (but then why not in 5.5?).

As a follow-up, I have just taken the source code of this problem and saved it twice as HTML docs, one without the HR.  I took them to the laptop (running IE 6.0) nd opened them without a problem.  While there are difficulties with IE and XHTML the problem appears to be more with how IE deals with XHTML on Perplexus.  Can do no better than that, sorry.
