I get the above error all the time now since a few days ago. I suspect that it was introduced by some automatic update from MS, but I don't know which one, or I would uninstall it! It seems to be getting more frequent also. It occurs on websites which were previously OK. Normally, I can accept the error and continue, maybe needing a refresh, but on one particular site, clicking on a link always causes this error, and the browser refuses to open the page!
i am using IE7 and XP Version 5.1 Build 2600.xpsp_sp_2_gdr.070227-2254 : Service Pack 2
Thanks in advance,
