Comment 54 for bug 403421

OKAY! So... I think I have a lead.
If you monitor the activity of the axis. They are only ever active when you have both eraser and pressure stylus enabled. You need to expand the the box below the test area (in hardware tab) to see the levels of activity of the axis. But when they are both enabled it doesn't work at all. When only one of either is enabled, you can draw, but with no pressure.
One thing I'm curious about though.. Is the "link" option, because there seems to be an important connection to the functioning of the pressure and having one or both of the features turned on.
The problem I've noticed is that you can "link" them together, whatever that does. Under the "hardware" tab, but it never saves this linked setting. Seeing as you need to restart the program for the other settings to come into effect, I'm assuming the same goes for the "link" setting, but the link setting cannot be saved.
Perhaps the two parts of the pen need to be linked to work, but cannot be linked?
Also, I have also noticed that when I cannot draw, the x and y coordinates go to extremely high values, although they seem to be normal values while I am moving the pen. This can be demonstrated by drawing a 3D box, moving the mouse about one can see that the box has normal dimentions, but while the mouse is still, the box stretches to an extreme size in some dimensions. So it appears that when the pen is idle the x and y readings go crazy.
But I first advise investigation into the "link" settings. Thank you.
Best of luck. Looking forward to a solution.
