I am using Safari 2.0.3 on OS 10.4.5. I click once on the "back" button and it takes me back numerous times. If I hit "submit new thread" right now, it submits and then jumps from page to page, back and forth. I'm not even sure how to explain it. Is this an indication of some software conflict? My mouse is charged and my BT keyboard has fresh batteries. To add to this my griffin powermate seems to have a mind of it's own. Is this normal for it to turn the volume up or down and randomly pause and start movies while watching them in DVD player?
