Re: I can't move the screen

just had this same problem tried everything to fix it and then i realized in the upper right hand corner if you click on the video camera icon it will show 2 video cameras, a sims 4 camera and a sims 3, somehow mine clicked onto sims 3 which was causing the problem, once i click sims 4 camera everything went back to normal and i can now drag and move, hope this helps!
