I set my trackpad and my mouse to have the secondary button function.

Everything was working normal until like 3 days ago.

The secondary button continues to work on every other area of the macbook except for the dock.
When I try to click on any app on the dock with the secondary click it simply won't work.

I checked my dock settings, and everything seems to be ok.

It's getting kind of annoying having to open the app to quit it and everything else and I can't figure out what's going on since the secondary click works on every other area of the macbook.

Could anyone tell me what to do to fix this problem?

Thank you
