I do occasionally see "not responding" at the top of the window. Is that the kind of hang you're getting, or something else?

I can't recall what happens with the Taskbar, but you should be able to change windows using either:

  • Alt+Tab, keeping Alt held down until an overlay appears, then tabbing to the desired window
  • Windows key+ Tab, to click-to-switch on the current and any other desktops
