When betatesting applications, many UI quirks tend to repeat themselves over and over again – it looks like Marx was right after all(history repeats itself). Anyways, look at the screenshot below:
The texts in the red circle(I drew that in btw) are clickable in order to change options – if you can find them.
Every platform has established “platform UI guidelines” – those become patterns and burn into user’s minds. Palm OS users assume that things with a frame around them are clickable – and since these labels dont have a frame, their chance on getting a click is low. One could say that they don’t afford clicking.
Today’s UI hint is short and sweet: If you want users to click on something, make it look clickable. Ah, and I cant repeat it often enough – keep to the platform standards!
