I use the installers of Freecad 0.13 on Vista and Windows 7 and I always loose snap after a while. (type exeptions error). after that I can't draw anything by clicking in the 3dview. I also tried other versions but it's the same. Right now I fake assemblies by fusing parts and then if they are each 0,0,0 move them into place, rotation axis and so on. What should i do? I think snapping is The most important part of CAD. Maybe there is something wrong with my preferences or there is nobody else using this in windows...
