Hi there

I hope this is the right place to post this, apologies if it isn't, and many thanks in advance for any help that can be afforded to me.

I have SketchUp 2022 installed (22.0.354 64-bit), along with FredoSpline 2.3a and LibFredo6 13.4a.

For some reason when I try to use FredoSpline, nothing happens, none of the buttons do anything. Any ideas? I've attached a gif that shows what I mean.

Many thanks.

Paul
