Mint 17 Cinnamon 32-bit on a desktop built for XP, nVidia GPU so the nVidia driver, 4 GB of RAM
I know (mostly) what I'm doing, so I move my mouse fairly quickly. About half the time, control of the mouse is taken away from me, and the cursor flies around the screen, often clicking even though I have NOT clicked the real mouse. Naturally this usually causes chaos, and I daren't write any important code until I can be sure my program won't get saved with bodge nonsense in it. I let go of the mouse and wait - after a few seconds, the cursor settles at the top right hand corner of the screen and I can go back to work.
In an attempt to bypass this, I have turned Expo off, screen effects off, mouse acceleration and sensitivity to zero (and tried full then zero). No change in the behaviour.
This behaviour also occurred in Mint 13 Cinnamon and was not changed by a fresh install of 17 (though I kept the same /home). Is there a way to delete any and all cinnamon-settings and effectively do a "factory reset" of Cinnamon? Starting a fresh login session does not change the behaviour. And maybe this isn't Cinnamon at all?
Unless I get this sorted soon, I will dump Cinnamon and use XFCE instead - which would be a shame, as Cinnamon looks so much better (and better utilities IMHO).
