It's been a while since I've done this, so I need a refresher. I'll start by saying I'm in Windows 10. I go to Tools, then Curve Creator, then load a qidf file and then I click on Show Curve. I'm familiar with the bug in GUI, that the curve doesn't show and instead I get a rotating blue circle. I can't find the Quad file, either in Virtual Store or in the Quad folder. I don't think I need Administrator rights to these folders because I've "unhidden" them.
I must be doing something wrong. Like I say, I haven't had to do this for quite some time.
