Trackball problem
About a month ago, my left Logitech bluetooth trackball button stopped working to attach or insert a file, as when I want to attach something to an email, which I do a lot. Otherwise it works perfectly. The only way to correct this is to reboot the Mini. Switching to my Logitech bluetooth mouse, I get the same issue. I've tried using a different USB port on the Mini....no change. A reboot fixes the problem for a few days only. Since a reboot fixes it, my guess is that it's an issue with this late 2012 Mini. Thoughts? Thanks.
