Placing 45 degree tracks
This is completely self inflicted.
Before I discovered double clicking on a bend to mitre a 90 degree junction, I found the place where you can tell it that you want to hand place tracks with a 45 degree option permanently enabled.
I turned it on and now I dearly want to turn it off, but blowed if I can find it again.
Where is it? I have been through preferences, defaults, styles, design technology, grids etc and my right mouse finger is worn out from all the clicking. I know it's there somewhere because I turned it on.
