Solution: I noticed yesterday that XQuartz was behaving normally when my laptop was not connected to the Apple Thunderbolt Display. Resetting the Thunderbolt Display solved the problem.

Essentially, X11 does not seem to understand touchpad actions (for example cannot close X11 windows, cannot drag them around, etc.). This problems also affects programs that rely on X11. Has anyone experienced (and ideally solved) this problem? Thanks in advance Roberto Roberto A.
