Hi Purty64, yes, normally you would have pressure sensitivity. Are you running the latest release (Alpha 3)? Did you do the thing described in my email moving away the qt.conf file? This should hopefully do the trick.
The eraser and zooming by pinching are not supported yet, but this is on our todo and will come soon in one of the next alpha releases.
Please let me know if the qt.conf thing makes pressure work?
Cheers,
Niels
