Comment 7 for bug 1191098

What distribution is this?
cat /etc/issue

I'm not 100% sure, but If you are on Ubuntu 13.04 or later, I would remove python3.2 and friends and let apt install onboard's dependencies. This will probably install python3.3. Onboard itself only requires >=python3.2, though.
sudo apt-get remove python3.2, python3.2-minimal, ...
sudo apt-get install onboard

Besides, we'll need to prepare a new snapshot for you. There have been changes due to Bug #1210575 that resulted in yet another new click strategy. The previous one I described above is still there, but only as a fall-back. The behavior should still be the same, though, right/middle dragging works here in either case.
