Invokation of drop-down menu from f.lux menu icon fails
I second the concern of the OP of the post linked here. It's the recurring issue appearing either after each restart or some unidentified reasons: I can't access the preferences and all the UI elements of this utility by clicking its menu icon unless relaunching it. I can tell it is running by observing the dimming I set in its preferences but other than that the effective control is lost. I use the latest version.
Which version of macOS?
We have noticed that it does not respond for a few seconds after launch, and I am still not sure why.
For some reason I'm not receiving any mail notifications about new responses so wasn't aware of your reply.
My OS X is 10.7.5
The latest version of f.lux
It appears only "About f.lux" and "Preferences..." menu items don't recognize clicking. The rest of drop-down menu items is OK.
You may want to take a look at the video screen-capture I uploaded to YT.
