First, thanks for the great themes you all are putting out. Very professional and clean!
I noticed with the 1.02 version of Expose that the the thumbnails on the home and category pages aren't working as they should--both on my install and on your example install at kriesi.at
It seems that the large, popup image is being displayed over the smaller image, and when the rollover occurs, the smaller image then appears, but the popup box is empty (just white).
Can you see where the bug is here? I'm guessing that Expose 1.02 was the update for IE9, correct?
