High Sierra - clicking on dock application causes dialog box to open
I have no idea as to how I caused this, but cant seem to find a way to reverse this behaviour.
Clicking on an application in the dock causes the application to open - as well as an additional dialog box.
I dont want the dialog box to open - just the application (see screenshots).
When logged into a different user account, clicking on an application in the dock causes the application to open only, not the additional dialog box - the way I would prefer it.
So clearly this is a setting within my user account only, but I have no idea as to where this setting may be.
