When does a sorcerer learn new spells?

[Fomalhaut]

Now, I am perfectly aware of the Charisma restrictions and my sorceress can throw spells and everything, there is just one weird thing...
When she moved up to Level 2, the "choose a spell" screen didn't pop up, so she managed to learn Level 2 spells (like Melf's Acid Arrow) only at Level 4. Is this normal?

[Kipi]

Can't remember at the moment the exact progress of Sorcrer's spells, but it's slower than wizard. Perhaps it was at level 3 when they get level 2 spells, can't remember. But it's normal

Yup. I didn't know for sure, but then I looked at my NWN booklet and it's true. You should however be able to cast more of your spells.(in number a day, not more spells)

Yup sorcerer gets ridiculously few spells so choose carefully
