So....you have been working your Kninja butt off in QBO....and you have LOTS of windows open....but now it's time to go and it's going to take forEVER to close all those windows.
Noooooo problem for a Kninja!
Go to your original tab....the one that opened up when you logged in.
Log out of QBO on that tab and all the other tabs will closed down!
Kninja Power - BaBAM!!!!
