Okay I did something. Not sure what. In fact, I didn't realize I changed anything at all BUT alas there is a change
I changed a line somewhere in a css that made a subcategory go wonky in both FF and IE8.
The prime example is on this page
http://www.baby-land.com/store/On-The-Go.html
In ff and IE8 it's all block form but in Chrome it displays the way I want it to.
yes I have and am using firebug and I can't see it. Ugh!!
someone please, find it in your hearts to point me to the right direction
