Yes, sometimes it is the very little things.
For months, our printer gave me fits. It was "wireless" although it seemed that every time I tried to print from my computer, it couldn't communicate. It used to work fine and then it just didn't. Shannon is a computer guru and even he was getting frustrated. So one day he told me just to take the printer and hook it up to my computer with the USB and forget about the "great" wireless capability. Oh what joy it is for me to click the print button and paper actually comes out of the printer.
A happy little thing indeed.
