Just to let you know, the 0.7.7 update didn't fix the zoom factor problem on my computer.
The app will correctly LOAD "0.8", but will SAVE "0,8" and will later get an error when trying to load "0,8".
Also, even after a successful load of the "0.8" value, the zoom factor is still not applied to the gadget when it's displayed.
Hope that helps, keep it up!
