robotgoblin: The Raise Dead spell only works if you manage to cast it within a certain time of the character dying.
I'm not sure about the timings, but I think it's the following:
Normal - 3 minutes per point of skill
Expert - 1 hour per point of skill
Master - 1 day per point of skill
I'm not positive, but I think the Resurrection spell has pretty much the same timings for a character who's been eradicated.
These are always immediately after combat, so that's not the issue.
ZFR: I believe you have to left click on it in inventory of a live character, then left click on the large charcter portrait on the right (the one where you equip weapons... etc). Then will the cursor change to "select target" and you can click on the dead character.
(I haven't found any of raise dead scrolls, but that's how others like remove curse work)
I will try that... I've always clicked on the portraits at the bottom of the screen.
