Reproduction:

1. Create a new character

2. Sex: Any, Race: Any, Class Cipher or Chanter (most likely any that choses spells/powers/phrases, etc)

3. Chose any two powers.

4. Deselect one of the powers by clicking it again.

5. View the power description on the right without moving the mouse.

 

Expected Result:

The power description should follow mouse-over as it did before the spell was deselected.

 

Workaround:

Move the mouse cursor off the spell it is currently hovering over and back over it (or any other).  The power description will show the correct information.

Alternatively, select any spell (including the one deselected) and the description corrects itself.

 

Impact: Minimal to none.  The problem corrects itself by the time both powers are selected.

 

Nice find, Nefron. That small issue has been noticed and should be fixed in the future.
