Comment 2 for bug 168646

I am also having this problem 0.45.1 on WinXP SP2. I also tried I updating the gtk libraries to 2.10.13 (installer from http://gimp-win.sf.net/). I updated inkscape to Inkscape0712281743.7z from the nightly builds. Same problem.

GIMP for Windows (version 2.4.2) from http://gimp-win.sf.net/ also has issues, but I am not seeing the exact same behaviour.

Here is a more detailed description of the behaviour:
  - The pen in absolute position mode works
  - If the mouse is set in absolute position mode, the cursor can get stuck, but taking it on and off the tablet a few times the cursor will start to move again.

  - The pen in relative position mode moves the cursor, but Inkscape interprets the position as if it it were in absolute mode
  - The tablet mouse in relative position mode never moves the cursor, but is interpreted as being in absolute position as indicated by the ruler guide markers (can't see the cursor, but can see the guide markers move.)

  - The right click context menu does not pop up with either the mouse or the tablet.

The right click problem is fixed in Inkscape0712281743.7z

Summary, relative mode is broken, absolute mode mostly works.
