Whenever there's a hiccup in my Metro flow, I have to rack up around a foot (30cm) of total mousemovement to get my cursor over to the Metro panel and put things back on track.
There's no denying that it's pretty odd at first -- we don't know about you, but we've never dreamt of titling our mouse all over the place, and even if we did we probably would have envisioned the movement to actually impact the navigating experience in some shape or form.
