I had this problem pop out of nowhere a few days ago where the dock icons stopped bouncing, the "little glow marker" underneath the current open applications stopped showing, and the right click option on the icon to close the application disappeared. I usually have several apps open at the same time and not being able to see which ones are open is very frusturating! I have already went to system preferences and made sure the "animate opening applications" is checked but still no bouncing. I really need the glow underneath the app to see what is open as well. when I right click on an open app icon it should say "close" but instead it says "open" just like if the app was not running at all. If anyone can help me at all PLEASE post any info you think might help. Thank you in advance for your time and effort.
