 > The code already implements that.
 You mean (in case of a Wacom Graphire) [source:haiku/trunk/src/add-
 ons/input_server/devices/wacom/TabletDevice.cpp#L288 line 288 in
 TabletDevice.cpp]?
 >Cutting of a range of the pressure is not the way to go.
 No, and it wasn't my first intention to do that. I was going to use only
 this line:
 {{{
 if (pressure <= MIN_CLICK_PRESSURE && mode == MODE_PEN)
 firstButton = false;
 }}}
 But this caused Wonderbrush to ignore the pressure-levels below
 MIN_CLICK_PRESSURE, so drawing thin lines didn't work anymore.
 >You need to find the place in the code where it uses the proximity as a
 threshold for the click. This value seems to be too low for your tablet.
 Since this is obviously tablet specific, and I even remember this value
 being different depending on where you touched the tablet, this should
 definitely go into a future preference panel.
 Well, I had a more generic solution in mind. But a preference panel does
 sound good. :)
