I have just started using blender and am still learning how to use it. I have very little knowledge about most technical things (such as API, F-curves and a lot more), so I hope I am given an answer I will understand. Anyway, the problem is that every time I try to open the user preferences (I am planning to use the ATN? landscaping tool, for my first project), the whole program immediately becomes unresponsive and I can either shut it down or ‘search for a solution on the internet’. It is probably some kind of problem with my graphics card (I have a laptop) or RAM or something (again, I know very little about this kind of stuff), but i might have missed something. So please help me and try to give me a solution.
