Thank you for the demo page of the bug.  I have confirmed that it is a bug in 
IE6 
and IE7, and I have worked up a solution that I will deploy shortly.

The bug occurs because IE6 and IE7 do not use a standard Function prototype on 
the 
submit() function, but instead use a natively bound (proprietary) function call.

The solution I worked up seems to operate correctly, but I strongly recommend 
testing all your various scenarios after installing the new solution, because I 
have 
to assume that IE will pass all the arguments correctly.  It SAYS it will do 
it, but 
hey, it's IE, so "trust but verify" is the best approach.

The solution will be posted as version 3.0.1.
