Comment 3 for bug 757972

This is also affecting me.

To add on, it affects not just easystroke, but any other app that uses mouse right-click.
Further, this behaviour seem to make the right mouse click is "stuck" once you click on it. In some cases, it seem to extend to left-click as well. So in Google Chrome, the grab to scroll extension is stuck with it as a result.

For me, when it goes into this behaviour, I cannot do left click, until I do a few right clicks and the system snap out of it.
