That's really helpful as I never noticed the three variant choices before (or if I did I didn't understand what they were or the differences between them, so left them in default 'radius').

For some reason, in creating an ellipse, I always held down the shift key. Now here's another oddity, depending on which of the three you choose from and then whether you choose shift or ctrl, the node positions vary. See screenshot:

About my vid egg, no problem & understand (that's why I mentioned no viruses etc). Zippyshare is a free file sharing service that works the best for me in my location. And yes, you have eliminated No. 4

Now I know why I was getting such weird node angles and messing around with rotation values of 0.0025 lol.

Thanks again.
