Leviosaurus, the symptoms you're getting are the exact ones I get when I have a sh@tload of saved games. When the game wouldn't save, I delete a ton of saved games and it works again. I'd guess it has problems when you have between 100 and 150 savegames but I'm not sure.
if you accidently click a previously saved game it will just make a copy of that and put it at the top of the list.
WTF is that???!!! I've had that happen many a time and it pisses me off! Is this a bug or Raven's idea of a sick joke?
And what's the deal with that @ssinine pointer. Sometimes the games scroll when you don't want them to and don't scroll when you want them to. Why couldn't they just make a sensible and easy-to-use save menu like Deus Ex.
I love JK2 but I think the savegame menu is a joke!
