Hey,
Just wanted to share a tip for an issue, which I didn't find an answer to. I had a problem with Inkscape not working properly with a Wacom Cintiq.
It allowed me to click a button on a given tab only once. E.g., after clicking on the Zoom Tool, I wasn't able to switch to a Pen Tool etc.. The same with other dialogs.
After a quick search on the Internet, I found out there is an "Input Devices" dialog, which you can access by going to Edit>Input Devices. It recognized only the mouse controller, so I figured this must be the issue.
As a side note, when I click on the Preferences/Tools button on my Cintiq it says "Wacom tablet driver not found". It's something I don't mind because even though it says that, the tablet is fully functional.
Anyway, what I did was, after closing Inkscape, I went to Start Menu and typed "Devices". In there I found "Wacom Professional Service" and clicked on "Restart". It resolved the issue.
Now Inkscape does see the tablet, and it works properly allowing me to click on the things I want.
