I can't seem to find any information about this, but I just installed my student copy of Solidworks 2012-2013. My problem is that when i click my middle mouse button to 3d rotate my part, It auto zooms to where it thinks i want to go. If i hold it down I can go on my own, but a fast click auto zooms. I cannot figure out how to change this. Anyone had this problem/how to fix it?
