It has happened a few times now, manipulating the object with the mouse and it jumps more than half the window width. I think it was back to where it was, but not certain. Can't get my finger on it, so heads up here, in case others notice it too. It was a fairly simple model so it isn't likely to be rendering performance, more like getting a wrong mouse position maybe. ----- Unless specifically shown otherwise above, my contribution is in the Public Domain; To the extent possible under law, I have waived all copyright and related or neighbouring rights to this work.
