I can't click on an app icon in Launcher Dash in 16.04, how to fix?

I just upgraded to 16.04 last week and moved the launcher down. Since then, the app icons in the Launcher Dash are un-clickable. When i try to click, my click does not go to the launcher dash, but instead goes to the window in the background. That means i always have to use my arrow keys to navigate, and that gets kinda annoying because

• i can't drag an app from the Launcher Dash and pin it to the Launcher.
• i need to press my arrow keys many times to get to a result all the way at the bottom
• and sometime i make a mistake and open a window i didn't mean to.

How do i fix this?

Solution 1:

Try to reload gnome screen by pressing ALT + F2. Then type "r" into the input field and press ENTER.

Solution 2:

I had the same problem and I just typed "Unity" in a terminal and it seemed to fix the issue.
