I don't know if this is the right place to seek help but have found no help else where. Script Errors on IE 7 when trying to print, I get script error messages even thou script debugging is turned off. I can not print any web page at all, If I do preview then I get a internal error and still no printing. Last week, I completely rebooted the computer and deleted and re installed IE 7 and that worked for 1 week and now I am back to the same error messages. What is happening and can anyone help me fix this
