Spending most of my web time in Opera, I had noticed that on one of my PCs, hovering over a hypertext link (i.e. <a href="..." ...>) had ceased displaying the target of the link in the UI, and there didn't seem to be a setting to make it appear again. Even when upgrading, that annoying behaviour kept stuck.

As one can expect, it turned out to be simple to fix, just not obvious in the Opera UI. Here is the procedure:

1. open Tools / Appearance
2. click on the Buttons tab
3. click on the Status category
4. drag Status field label to the toolbar where you want it
5. confirm by clicking OK.

The problem with this is the fact that Opera gives no visual cue about the fact that text strings like Status field are actually draggable objects like more obvious ones.
