Forgive me, I don't know what the EDGE terminology is for black dotting (I'm a XIM3 user). But in the XIM4E beta, I've noticed that black dotting is identified by flashing red lights. Is this accurate?
Assuming that it is... I have my sensitivity set so I rarely black dot on my movements but I notice it flashes red with simple up/down movements regardless of how fast I do it. I can get it to flash red with fast left/right swipes but any up/down does it. Is this normal or a bug?
