lost back button
At about 2:15 mst today I suddenly had no forward/back buttons on Safari. I restarted Sarai, restarted my computer, went to view and re-dragged the buttons to the toolbar even though it shows that they are there, and made sure all updates were done. Now what??? I am using history (and Firefox) to navigate about the interweb.
MacBook Pro, Mac OS X (10.6.7)
