Anyone else having these issues? NOTES APP The cursor vanishes and I need to quit and re-launch the app to get it back. This happens after the app has been open for a period of time. Loss of Sound in certain apps After my Mac is open and running for a period of time some apps no longer chime or play sounds. Taking a picture of the screen Command + Shift + 3 is one of them, MS Outlook is another, etc. NOTE there is nothing wrong with my hardware as all other apps play sound just fine, and sounds for MS outlook and such are re-stored after a reboot. This has to be a software glitch in Mountain Lion. No I have no re-installed my OS or done a clean install as it would probably be a waste of time since I doubt it would fix the problem. I have taken these steps and spent many hours in the past only to find out that it did not solve the problem.
