I have tried this and the weird thing is that it works depending on the website that you go to.

For instance it works for google and also to get info from the api of a russian wiki:
However it does not work for the api of a french wiki:You get the runtime error "Object required"

Also I tested it yesterday for booth wikis and I think it worked then (not complete sure if I tested it on the French one). Since yesterday I downloaded a new version of the IE. Anybody an idea what the problem is?
