And just to clarify, because I have a feeling what answer will be given. I understand that with VC running there's a two way communication over USB that could be slowing things down compared to standalone. My comment is that it's more noticeable now than it has been in the past.
When I first got my TI2 a few months back, I was curious how much snappier it might be compared to my previous TI. So i was specifically looking for this sort of lagging behaviour like I used to occasioanlly see with the original TI. Never saw it though, so I was pretty pleased. That's one reason this stood out to me when I saw it now. Again, not a huge delay, maybe a second or two, but noticeable.
