Does work for me. But with playing around, I have found that sometimes, for example if you do an "Escape" two times consecutively, it's blocked. By some other activity , for instance pulling up a selection window on the screen, it's activated again. But I haven't yet found out the exact circumstances.
2.1.3 is the official recent version, whereas 2.2.0 is the development version. At the time in RC, Release Candidate state, and quite stable and usable. It has enhancements in several fields, like user interface, hatching, dimensioning, plugins and more.
