Comment 21 for bug 1401593

This bug is not about the "spacebar issue" (probably https://bugs.launchpad.net/inkscape/+bug/1400234 ) but about an option to disable mouse panning. You can find it as a checkbox with the text "mouse move pans when space is pressed" in inkscape properties (ctrl+shift+p)->behavior->scrolling.

You can work around bug 1400234 by disabling pressure-sensitive tablets in inkscape properties (ctrl+shift+p)->input/output->input devices (uncheck "use pressure sensitive").
