Do android launcher apps affect other apps or not?

I installed nova launcher and had updated some apps (facebook, viber, google+, and dropbox) some hours before installing it. I setup the launcher and it was working smoothly and fine, but then after some minutes it showed up a message that facebook is not responding, then after some minutes viber is not responding and then google+ and dropbox are not responding. at first I thought that only newly updated apps are not responding but they were, I don't know why this message Wes showing up. Any method that this message doesn't show up and doesn't interrupt me. for now I have deletd those apps.

no, launchers shouldn't have anything to do with other apps. unless you are talking about the manufacturer widgets. something like HTC Sense's widgets wont work on 3rd party launchers, same with samsung and moto widgets. but apps themselves (especially from the play store) should not be effected. i say download again and see if they come back. not sure why they would though. i have all those apps (except viber) as well as Nova launcher and dont have any issues....even after i just updated them
