Issue started fairly recently, but I'm unable to pin point an exact cause.
Phenomenon: When waking the computer from sleep, Alfred doesn't respond to shortcut until wireless connects; when wireless is disconnected, keyboard shortcut is unable to call up Alfred; when wireless reconnects Alfred flashes (once for each pair of times the shortcut was previously pressed). When wireless is turned off, clicking the button in the menubar does nothing for a while, then flashes a bunch after sometime on the top left corner of the screen. The issue seems Infinitely repeatable.
A gif of this in action: While not shown, on each operation with airport, the shortcut for Alfred was pressed. http://d.pr/i/18buP
Alfred v2.4.2 (432), on OSX 10.11.3
I suspected iTerm and F.lux, but the issue persists after both are quit.
Please advise!
