I am having a problem with my screen freezing in Wildfire 2.0. I'll be working with an assembly, and have multiple windows open at once. When I go to switch between two windows, often the one I switch to has a frozen image on it. I activate the window, and try to spin the model, and the image does not move. I have to go to file>open and re-open the part to get it to work. I know that as I try to spin the part, it is actually moving, I am just not seeing it because whenI re-open the part, it is at a different orientation. Has anyone else had this problem? Does anyone have any suggestions?
