Bug in axes - angular lines

Hi.

Im experiencing a bug in my sketchup. When i group something the group jumps to another place. Also when I copy and paste in place it jums to another location.
Also my whole model is skewed inside groups lines became angular.
I did already start a full new model and redrew the whole model. but the problem came back.
Now I opened an old model and the same problem occured. Is this a aknowledged problem? And how to solve it. Because if i open these models with another computer it seems like the bug doesnt dissapear.

Share the .skp file so we can see what you’ve got going on.

If it’s not too large, drag the .skp file into a reply to this thread. If it’s too large to upload here, upload it to Drop Box and share the link.
