I only see Women's Singles as an option whereas the screencaps clearly indicate there should be Men's Singles, Women's Doubles and Men's Doubles too (possibly also juniors?).
Minor bug: the drop down menu for 2010 shows only present week at first, until you choose another year and then go back to 2010.
Minor bug: years covered are 1970-present, and indeed Peled's '70s results shows up where available, but 1970 gives an error message.
I think the first 2 problems you mention are xp related. The problems exist in xp but not in vista.
In xp you can see the men's singles/doubles and women's doubles by clicking on "women's singles" and then using the downward arrow.
The same goes for the previous dates at the beginning.
