Issue with pressure sensitivity

HiMy cintiq (21UX) works fine with Macromedia flash and with a handwritting program, the line is pressure sensitive and tapered but when I use toonboom the line is consistently the thickest setting with no taper and no pressure sensitivity.Solutions?

Hi - did you try: [Remove All Preference Files] in your pen “Tablet Preference File Utility”? First close SB and reopen it after removing preference files-romi : )
