Problems with RESEARCH BUTTON

1) if you research a spell you already know, a message in your system tab will tell you that you already know the spell => OK!

I'm not talking about it. I'm taking about:

2) if I research a new spell made with just 1 glyph (darkness, flame spire, etc...) it works fine

3) if I try to research a spell that needs a combination of glyphs (rock fist, summon rock) it doesn't work. No spell is shown and if
I try to cast it in prompt, it will tell me "you don't know this spell"

So I do think there's a bug with research button.
(by the way, I'm using Win version of the .017 client)
