I've been annoyed by this issue for a long time. I bought a Magic Mouse about eight months ago. At first I couldn't use it at all with my Mac due to the OS X system compatibility issue (but resolved later after upgrading my mac to El Capitan). But there is one bug that still holds -- the disconnecting issue. Sometimes it disconnects and reconnects automatically, and when that happens, there is about two seconds I can't move the cursor. Anybody encountered this? Solution? Thanks in advance.
