Ok, this is getting silly....
Bulya, I deleted the wiki entry on removing the GTK path, here is why...
When I deleted the GTK path(s), the tablet mouse worked perfectly in Inkscape, however I later discovered that the pressure and tilt did not (also in Gimp). So, I uninstalled all GTK programs and reinstalled GTK 2.10.13. I also uninstalled Inkscape and reinstalled 0.45-1 then copied over Inkscape-dev from October 18th. Now the mouse returned to its previous behaviour so (just to be sure) I reinstalled the Wacom drivers (latest) and no change.
So, to summarize -
With gtk paths, mouse doesn't work but pressure/ tilt does. Without GTK paths mouse does work but pressure/ tilt doesn't.
There must be a way to fix this as so many people have it working but removing GTK does not work for me, especially as Gimp makes far more use of pressure and that also fails with no GTK. As Gimp is also affected it must be due to GTK so for now I am going to have to give up on this one but I will post on the GTK forum to see what happens there.
Thanks,
Tony
