Hi All I've been using my MS Scuplt Comfort BT mouse since I got my SP3 weeks back, without any issues whatsoever. No disconnects, smooth as butter. Cue yesterday when I purchased a Bose Soundlink Mini Bluetooth speaker. While the speaker paired and works flawlessly, now the mouse is prone to lag, and stops responding randomly many times. Disconnecting the Bose BT speaker, and all is fine again. Any ideas ? Edit: sometimes when the BT speaker is connected and system sounds occur (obviously channelled to the speaker) the mouse will hang/pause/lag. Perhaps a bandwidth limitation on the built-in BT chip ?
