Are there any known problems with IE 7?

Yes, there are many.

The text is bolder than average.

Some sites don't work with it.

There is a list of 100's, but they are mainly coding problems.

If you are looking for a better browser, try Firefox, or Opera.

I am sure there is but I use it and have no problems and think it is better than Firefox so many other people claim is better and faster. I would disagree with them on that and say they probably have a lot of added junk to IE7 if it is running slow for them. IE7 is faster for me than Firefox.
