loss of keyboard short cuts and right click on mac

when i am editing on lightroom, after like 5 minutes of using it i loose the ability to use keyboard short cuts and right clicking. when i am outside of lightroom my keyboard and right clicking works fine. I have tried hitting esc and enter as some have said that has works and soemtimes it works but i am just wondering if this is happening for anyone else. My LRC is up to date and so is my Mac.
