I noticed a change with Picasa albums.
When you click the magnify glass on Picasa album picture it opens in a new frame (nearly full screen) with a black background which is much nicer than the previous same screen/white background.
You can also zoom in much more than before and it auto centres the frame.
All this now shows up artifacts and poor tracking! Damn! Well FWIW
Merry Xmas IIs'ers.
Edit:
Just an amendment..it only allows this enlargement and black background if the pics post are "larger". I found it won't do it on small images.
