Hmm... Ok.. Those values are from a 'Wacom Intuos3 4x5'... But I wonder where those come from.. See below. > What is their unit system? Each tablet has a physical size and a resolution. Those two values will produce the value ranges that are reported for x and y.

You might want to have a look at the 'KeepShape' option if the ratio on your screen and your tablet is not close (but they seems to be).

Where does the previous figures come from? However this would explain the problem you have with not beeing able to use the lower part of the screen as your tablet will be unable to send coordinates that will reach that far down if you put the BottomY at 20320. It would also explain why you can't use an area on the right part of your tablet. Remove the BottomX/Y options from your config and I bet your tablet will start working as you expect.
