I have several pcs notebooks (work/home) along with my new aluminum macbook and other macs......going absolutely insane when web browsing on the PCs without multi-touch gestures. I kept trying the two finger scrolling or swiping to move forward or back. I thought it was was broken until I realized that I can not do it on the PC I was using. I think I tried for 5 minutes trying to figure out what was wrong. Just curious is anyone else had this happen to them.
