slicing problem

Could someone, with IE 5 for the Mac, please check this link for me, and
tell me if the last image slice is moving down to the next line, instead of
being all horizontal?

It is splitting on my Mac at work... and I just want to be sure...

Can anyone explain why this might be occurring? It previews fine locally, it
looks fine on IE 6 on the pc... I've gone thru the page carefully and cannot
figure it out...

I'd appreciate a more experienced eye and brain with it...

Thanks in advance for your time and expertise,
