Trivial bug with my copy of processing; the icon displayed in the taskbar is the small version of the icon, so Windows 7 automatically enlarges it and it becomes fuzzy. I've tried resetting the icon to the one present in 'processing.exe' and in the start menu it displays the large version but not in the taskbar. I'm running the latest version of Processing and 64bit Windows 7. This problem also happens in the Arduino IDE, I'm guessing the problems are related.
