I've come to the conclusion that Inkscape is resisting me with a will of its own >.<

My tablet refuses to function in Inkscape. A little google-fu came across two known issues, one that is GTK+ based (which can't be it, because GIMP works like a dream and the issue was happening in both programs), and the other saying that Inkscape can't handle two pointing devices at the same time. I unplugged my spare mouse, and the tablet worked great ... for about 2 minutes. Now it's back to consistently not functioning, even after reboots/program restarts.

If it matters, I'm using a Wacom Bamboo. I've tried turning the pressure sensitivity off in Inkscape (with my spare mouse before I unplugged it), and making sure both the tablet pen and the tablet eraser pointing devices were set to screen (which they already had been).

I'm usually a better geek than this, but Inkscape just seems to keep foiling me. Any ideas?
