My system had a hiccup so I have reinstalled windows 7 and all software on top, including solidworks 2013.
It basically works, but there are two weird behaviors it didn't have before, and I've not been able to find any related options to turn them off.
1. If I click on a solid, it behaves like I've double clicked and shows me the dimensions in the generating sketch. Oddly, nothing else behaves like its been double clicked, and double click seems to work perfectly normally. This is actually quite distracting and annoying - thoughts on what option would turn this off?
2. Under certain conditions, the part or sketch moves, get reoriented, as though some kind of auto-zoom or auto-rotate had been executed. It didn't used to do this. (Example - sketch some simple shape like a square, then do a feature>rotate, the sketch will be rotated around at an odd angle for no apparent reason. You can put it back, but why did it move by itself?)
