Basically what the title says. I have a few tabs open in Safari and everything's working great but as soon as I start downloading a file and the downloads window opens, the whole mac slows down, animations get choppy, and bookmarks below the address bar have problem catching up with the cursor (what I mean by that is that I quickly mouse over all of them from left to right and about three seconds later they start turning dark grey like when you hover over them). The strange part is that when I close the downloads window, everything goes back to normal. Help? EDIT: Forgot to mention that this is on a Leopard install that is just a few weeks old, with everything updated and repaired permissions.
