Dimmed menubar on Safari


Sometimes my menubar goes dim when I open mail or sometimes safari. Activity monitor and force quit will not open. Restarting does not help. It is ok when first booted up but then fails again. Restarting in safe mode and then restarting in normal does seem to clear up the problem. Anyone have any ideas?
What version OS and Safari are you using?
Do you have any Extensions installed? Try turning off Extensions (from Safari Preferences) and see if the problem is corrected.
