I'm off to install IE10 on my Win7 machine at work here. See if it jives well with ADP. It probably does not, seeing that ADP never liked IE9, but I'm bored, so I'll try anything once.
Update #1. IE10 installed. Computer slower. Looks like IE9. Boo.
Update #2. Mazda Dealer website is borked in IE10. Usable, but looks like shit, just like it does in Chrome. And, as I feared, ADP does not integrate well. Switching back to IE8. Bummer.
