Just wanted to post back here that, since upgrading to firmware version 73*, I haven't gotten the rogue "Are you sure you want to shut down...?" prompts!
However, the first issue that F W posted about, namely "Volume up/down only trigger volume down, pause the music or do nothing", is still not fixed.
Can anyone on the KeyMouse team reproduce this issue?
Thanks and best wishes.
*(looks like this is still the latest available version for my KeyMouse Alpha 105, according to the latest KeyMouse software version available for this model, i.e.
v2.56)
