Hi Joe,
This may not have any bearing on your problem, but I'll ask anyway:
Are you sure those are valid IDs? Because my read of the spec is that
[ and ] are not valid in HTML element identifiers. The "id" attribute
[1] is of type "name"[2], which "...must begin with a letter ([A-Za-
z]) and may be followed by any number of letters, digits ([0-9]),
hyphens ("-"), underscores ("_"), colons (":"), and periods (".")."
[1] http://www.w3.org/TR/REC-html40/struct/global.html#h-7.5.2
[2] http://www.w3.org/TR/REC-html40/types.html#type-name
Does the problem still happen if you stick to IDs fitting the rules
above?
FWIW,
