I just started using the new version SU 2017. I am having a problem selecting and creating a "component". I am used to triple clicking on the newly made object, which selected all faces/edges, and then right clicking to select and create a component from the selection. Now the triple click doesn't work for me with SU 2017. I don't even get the blue edges on my newly created object. I have to drag a box around the entire object, which selects the object, and from that I can create a component. This can be very difficult, or impossible, to do when creating a component within or touching an already existing component. When I first discovered this problem i tried various methods of creating the component, but only boxing the object seemed to work. Thinking that I might have a bad download i uninstalled SU 2017 and downloaded again. Exact same problem. I am using Windows 10.
Has something changed with SU2017? As a side note: SU 2017 seems significantly slower that the previous version. I have a fast computer , good graphics card, and lots of memory.
