Thank you guys for your prompt replies Bill and Richard - I am using the standard Apple one button wired mouse. The cable outwardly looks fine but there is no obvious way to get inside the mouse to inspect the connections there. Tony - I will try trashing com.apple.Safari.plist from /tonyjohansen/Library/preferences but I guess it will take a day or so to see if that works. Steve and Jon - I will if it freezes again first unplug/replug the USB connection, and if that doesn't work or the problem persists will try my Belkin mouse I use on my iBook. I appreciate your help and will report any success / failure Tony http://www.tonyjohansen.com A Life Of Art
