I don't think this is an HTML problem... all current browsers will send
*exactly* the same request to your server whether you have escaped the
ampersands or forgotten to. (Assuming you haven't accidentally given one
of your variables the name of an entity, in which case the non-escaped
version will break.)

I may be able to help if you can point me to a misbehaving page (though
authoring problems are OT on this list really).

This is correct - using %26 takes away the special meaning of '&', so
that you can put an ampersand in a field value. eg.

This isn't the case; something else is going wrong.

But then how would you include a " character in an attribute value? :-)
