works for me as well?
I don't see any problems.
Perhaps you need to clear your cache? (people are always telling me that anyway)
I know with FireFox on a Mac that the x-cart fields sometimes "timeout" or something so you can't input data into them? You close it down and open up again and its resolved itself.
Unfortunately, I am obviously more novice then you are so there's not much I can do to help

By the way congrats on figuring out 4.2 (I'm still trying)
I wish I could figure out how everyone changes the top area in x-cart.
But you are doing a good job!
If it were me, it would have been moving the search bar that broke it.
I would have done something wrong in the code.
If it was HTML I'd say look for an unfinished tag.
Not sure if there is an equivalent in x-cart?
