Ok, first things first, 'Block pop-up windows' is UNCHECKED. I switch back and forth between Firefox and Safari because for some un-earthly reason I cannot get Firefox to play embedded videos. Yet Safari plays them fine. So this morning I go to Bestbuy.com. Want to look at the weekly ad. I enter my zip code, nothing. Click 'go' over and over, nothing happened. I turn off the pop-up blocker, nothing. Yet my wifes Macbook opens it just fine. I tried a different site that had a 'help' button, suppose to pop open a small window with information, wont open it there either. Any help on this??
