Has anyone else encountered problems with the menu bar randomly deciding or not deciding to display icons or options? Recently, it seems that when I reboot by Powerbook 12 (reva), there's a good chance that the icons for Bluetooth, Fast User Switching and iSync will likely be gone from my menu bar. Airport, volume, battery, and any external menu bar items show up withou any difficulty. It seems to be somewhat random, and each time I check in Preferences (or in iSync prefs) the option to show the non-appearing icon on the menubar, is still checked. Any help would be greatly appreciated.
