Thanks for your prompt reply. The error 1518 just cropped up this week and applies only to the web site of Liberty Bank, my financial institution. I log in with my proper user name and password XXXXX get the 1518 error message. IE stops working at another place when I try to use the bank's support section.
All my other websites opersate with no difficulty. I discussed with bank techs and we ran through a whole series of changes using Internet Options but to no avail.
Hope this helps
