Yes, it does happen every time I start to modeling something, even if it is not a cube. I think that my settings for wireframe, is there all the time, but even if I change the wireframe mode to another mode nothing happend. I guess that there is something in my cinmea settings that there is something wrong with, and I have had this problem for a little long time now, but I cannot fix the problem. I just wonder where I should change settings.
