Poly Fill not working on Win 11

I simply cannot get it to work where I can click on a poly in the 3D view and have it filled. Single click does not work at all for me. I can click and drag, but that's not useful because SP (still!) doesn't have backface culling. I tested older project files where I know left click to poly fill worked and it doesn't work there. I also tested older versions of SP and it still doesn't work. The only change is that I'm now on Win11 instead of Win10.

A final test was going to an older Win10 machine with the latest version of SP and the model I'm currently working on. On that machine left click to poly fill works as expected. Of course the two machines differ vastly in more than just OS, including the vid card. However, i know for sure that left click to poly fill worked on my main machine in the past and I haven't changed hardware on it. I've attached a log file.
