I get a confirmation dialog when I close ConEmu's tab.
Where can I configure that confirmation dialog only appears some process is still running?
I checked Settings->Features->Tabs, but I couldn't find a option for it.
Settings dialog has Search field. Just type Confirm there.

I would like to share my settings that helped stop those "Confirm closing console" warning messages when I run Git-bash.
Main->Appearance->Close confirmation, Thanks! – ironsand Mar 21 '14 at 21:39
