Ever since I have updated to 10.5.8, Leopard will continually freeze. I restart and it loads up all fine but as soon as I open something (Finder window, Mail, Safari etc) it will remain usable for about 30 more seconds until it just freezes with a blank screen (sometimes black, red or white) OR the screen image will freeze but I can still move the mouse except nothing is clickable anymore. I've resorted to starting up in safe mode to post this but has anyone had this issue before? Any help or suggestions? Please!!
