Can't seem to learn my spells/I'm just retarded and not doing it right? (screenshot)

[bigronz]

Whenever I try to load my spells from my inventory to my spellbook, I can't seem to actually click the spell into the slot. I keep clicking on it and nothing happens.

I've included a screenshot to show how far I manage to get: Any ideas? I'm an old EQ player from ~10+ years ago, and I'm sure what I'm doing is correct?

Sorry if this is wrong forum, not really a "technical" issue
