Every time I try to edit an actor's spell list (I've only tried it with custom actors, not existing ones) the Creation Kit freezes for a second, and then comes up with a crash message; the standard non-descript "Creation Kit has encountered a problem and needs to close" dialogue box. I click one of the options to send an error report and close the dialogue box, and the CK closes and dumps me back to the desktop, as expected.

So, what I'd like to know is: Has anyone else experienced this problem? If so, have you found a way around it, or has it been fixed with a patch I don't know about? Because it's really getting on my nerves; I'm trying to create a custom mage NPC follower for a quest, and this issue is stonewalling some of my progress on that.

Even though I doubt it has much to do with system specs, here are mine, just in case:

CPU: AMD Athlon 64 X2 5800+ Dual Core
RAM: 2 GB G.Skill DDR2 800
GPU: Radeon HD 4870 512MB
