I have a macbook 10.5.6 which is fully updated. I am having issues with safari causing beachballing and running hot / the fan running on overtime. I have tried the usual methods of resetting safari, deleting the pref file and now I am stuck. If I am opening a new tab I may have to sit for 30 seconds through a beachball. If I try and watch MLB.tv or any video content the fans kick in and the macbook runs very hot. Often during this safari freezes and will beachball. I have no internet issues as other macs and PC's run fine. The issues happen both by wireless and wired connections. Research has pointed towards a flash issue. I have uninstalled and tried old version but the same problem arises. Any suggestions?
