Same issue here through firefox. Switched to IE and it started working. Both the ATP/WTA site seem to only work properly in IE, it's almost impossible to open their PDFs in anything but IE
well sometimes it doesn't work with IE either
many times it didn't work in the last days, the old livescore was not perfect but much more reliable than what I've seen in recent days.
One thing that I especially don't like is that I'm used to being interested in stats by set and I'm mostly interested in the stat about "points won on return" : then I need to scroll down to look at that stat ... but then I need to scroll up back to be allowed to look at the next set and then scroll down ...
One thing I also don't like is that when I want to look at stats for matches of the previous day, when I go back after watching the stats of one match, they take me bakc to the present day instead of staying in the day I was looking at. The old livescore did it well.
