Yes, what you said makes sense. Only on my game it won't work like that. I changed the icon to a blank square, but when I click on it to "learn a new skill" there, the description of the old skill (one-handed slash etc.) comes up in the text area, sans any points in it. Therefore, I can't use that square to learn anything else.
Perhaps one must pay not just to unlearn a skill in one lump sum, but in several lump sums? I.E., a separate payment to unlearn every skillpoint in the skill AND a separate payment to unlearn the skill itself? If so, that is extraordinary... and negates the much-touted ability to try things out because you can supposedly "unlearn" them later.
I'll have to see if I have to pay a second sum to free up the box itself. If so, it's one more design decision that puts a <img src="/ubbthreads/images/graemlins/suspicion.gif" alt="" /> on my face.
