F24 Notifications Holding Up Power Off
I am having an issue, which just cropped up near the EOL of F24. What happens is when I try to log off I see a long list of Notifications regarding VLC - "Some applications are busy or have unsaved work" with a list of individual Notifications which say "VLC media player" on one line and "Inhibit by Caffeine" on the next. (I have closed all running instances of VLC at this stage). I tried to attach a Picture but it refused me the ability to do so. Although it does Power Off, eventually, I am thinking that these Notifications are referring to something that is delaying the shutdown. How do I get to the bottom of this issue? If I never use VLC, while in any given session, this does not happen.
I am using Caffeine to keep the VLC running and not allow a Suspend while playing (I used Tweak Tool) to set that up and it works well (I have the Notifications Off in the settings shown in Tweak Tool). In normal operation once VLC is closed, Caffeine goes off as it should. Any help would be appreciated.
