hi, i recently bought a microsoft sculpt comfort mouse, and am now using it on my thinkpad x230 that is running win 7 64 bit. however, the annoying thing is that the mouse lags very often, and seemingly at random. the cursor is frequently lagging my hand movement. i read somewhere that this maybe due to some interference from devices such as mobile phones, nearby routers etc, so i have removed these from my vicinity and that seemed to help somewhat. but the lag is still there, so i thought it might be an issue with the laptop-mouse pair itself. a check with the Device Manager turns up 2 items with exclamation marks: "bluetooth peripheral device" and "unknown device", both under "Other devices". does anyone know if these are the causes of my laggy mouse? if so, where can i get their drivers from? (google searches turn up quite ambiguous stuff). if not, anyone knows what may be wrong? many thanks.
