Whenever I try to edit, or add (or even double click on a dialogue topic) in GECK, it just stops working. It crashes. I'm using Windows Vista Home Premium, 32bit. If anyone has any information that could help me, I'd appreciate it. Note: I've tried running in combatibility mode, and running as an administrator. Edit: I just tried the same thing on the Oblivion construction set. It has the same problem. I did some research, and it was a common problem between Vista users. Bethesda, you had three years to fix the problem, yet you haven't? Honestly, if you have to make the construction set user friendly (by not changing it all), then fix something that stops a majority of mods.
