[quote="pjj"]Yeah, this is tricky
After having opened Unit converter and picked appropriate unit set, e.g. Time, you click once on a 0 at this particular unit, which will be your "base", e.g. h (hour). After approx. a second input box should appear, so you will be able to write down your value there[/quote]
Actually no. After clicking once, nothing happens. But your description gave me an idea, how it could happen, and here it is:
(1) Click once on 0 (as you said). This will have no reaction, no matter how long you wait.
(2) Click on the 0 a second time (make sure that you wait long enough so that your clicking is not interpreted as double-click)
(3) Wait a second (as you said)
(4) Now the 0 turns into an input box in which you can input your figure.
So the crucial point is (2) above - a second click is necessary.
