Up until today Picasa imported fine. I was running the last 3.8 build for Windows XP and then when Importing from scanner using Twain driver Picasa shows "Acquired 1 files" but no thumbnail and no way to import anything. image0.jpg is 0kb in the temp folder. Tried rebooting machine, etc., but same thing happens. Upgraded to 3.9 and same thing happens. Google, why is Picasa doing this?
