If I search for something on wikipedia with google and try to click through to one of the articles, IE8 prompts me to download the page as it doesn't understand the mime-type.
This has not always been the case. It started about 2 weeks ago. I had not changed any settings or installed any software. At the time I checked my windows restore points and there were none within a few weeks of the symptom occuring.
Does anyone have any possible explanation for such behaviour?
32bit Vista SP2, IE8
OK. So this only happens when I try to click through to Wikipedia from some other site. If I type wikipedia.org into my address bar and hit return it shows the page no problem.
