Hi Gregg,
I had something similar recently after updating to Blender 3.0 where I wanted to adjust my bevel by a small bit. I held down shift, moved the mouse but for some reason the bevel width was stuck at 0.02 and wouldn’t change unless I moved the mouse extremely far and then it would jump to a much higher value. Not holding down shift worked as usual.
When I created a default cube it was working fine, though, so I thought maybe something in my mesh was messed up. Will have to check if I can reproduce it, but hearing that you experienced something similar maybe this could indeed be a bug in Blender 3.0
