Hey everyone, I am updated to the latest update.  I never have had this problem.  I am working on a project I have been working on for a few weeks and went to hit play and it didnt work.  My hotkeys work but play, stop, timeline shortcut, record....none of them respond with the mouse.  I have never had this problem.  Just curious is there a fix for this.  Also sometimes some of the faders wouldnt respond either.  Very odd.   Been using Sonar for years and never experienced this.  I did restart the computer, opened up different projects and new projects and it still does it. 

Anyone ever have this issue?

There have been a few threads regarding mouse positioning issues on certain controls since the latest update. Not sure if your issue is related, but it could be. I'm seeing no mouse issues here at all on the latest release.

If it's a wireless mouse try changing the batteries.

Its a wired mouse.  I was on an older version, probably December 2016 version and it started doing it for no reason so I figured hey I will update and see if that fixes it......nope.  Very odd...Im glad my hotkeys work its just very odd things happen during sessions.
