madamspud169, have you recently changed your Anti Virus sotftware, or installed a popup blocker?The reason I ask is that I am having exactly the same problem as you, and it has only been happening since I installed AVG and Zone Alarm, and a popup blocker.
I too have followed all of the instructions recommended by other Abers, but I still cannot get rid of the script error message.I have uninstalled my popup blocker, but still the errors occur.I have run spybot and adaware, but still no luck.I am now on the verge of uninstalling AVG and Zone Alarm to see if it makes a difference.
