Thanks for your input. This is what I'm getting in IE: I have tried to set IE as the default browser (Tools - Internet Options - Programs - Reset Web Settings), but when I click on 'Reset Web Settings' button, nothing happens at all. I have the option 'Internet Explorer should check to see whether it is the default browser' checked - but IE after restart never asks if it wants to be set as the default browser. If I go to Firefox options, I'd see it's still the default browser. UPDATE: Opera works just fine. UPDATE2: OK, I've fixed it following this advice: http://windowsxp.mvps.org/ie/905915.htm All symptoms described above disappeared.
