[l2h] Fails to number figures: bogus "arguments too complex" erro r.

[Thomas Bewley]

John -
Try changing \times to \protect\times in your caption.  Each and  
every fragile symbol in the captions, (there
are typically a lot of them in math mode), needs to to have this  
\protect prefix.  See the latex book for what
fragile means, and see the associated .aux file that latex generates,  
and latex2html must refer to,
to see the mess that latex puts into the aux file if you fail to have  
this \protect prefix there...
cheers,
- Tom
