3D window is not working

[Anonymous]

Hello,

I have a problem with a 3D window in Archicad 21. It works normal at the beginning but after a while it shuts down and when I try to open it, it opens but the only thing it shows is a 2D window which is not responding.

If anyone knows what the problem might be, I would be really grateful, because it is really annoying. And I've already tried to reinstal the program.

Thank you

I would have guessed that you seldom if ever encounter a bonafide Mobile Workstation at a high school.

We had working computers for about 10 Years (as environment) but "they" didnt pay enough for the teachers which kept them running and "they" didnt pay enough to get "state of art" computers. So we teachers had to take the other way and now "let the parents pay" for functioning hardware in form of laptops.

Its not the way that i would prefer, but "they" let us no choice..
