Trouble sleeping...

[hugheba]

Um, for some reason sometimes when I return to my computer and move the mouse to make the screen come back up my top apple bar is gone and there is a scrambel of lines at the bottom of my screen, as if the dock ran all the way across the screen and is blurred.

I don't have my computer put itself to sleep, just have the screen turn off and hard disk spin down... but that might be what sleep is...

The only thing I've done lately was uninstall Norton Personal Firewall and Alcatel USB speedtouch ADSL modem drivers.

Is there a way to somehow do an install of system software to maybe repair what uninstalling those may have done?

They say down downgrade your versions of OS X but how can I install 10.1.1 again?

Any suggestions?

just install it starting with your original disk and go thru and update to where you want to be just like you did the first time. all your settings and preferences should remain untouched, but backup if feasable to be sure. I've done it and it works. note - apple mail seems to the only thing potentially effected. it may start asking for permissions again. click 'open anyway' and all will return.
