I often do models for injection molded parts that require many fillets.  Ill create a fillet and set the value at say 0.5mm then start clicking other edges to add to the fillet.  As I use the mouser wheel to zoom in and out of the model finding edges to fillet, I often run into the issue of the fillet size going from 0.5 to 10.5 unexpectedly.  For some reason me clicking away in the modeling window causes the radius value field to become active which allows the scroll wheel to change the value.  Is there any way to disable the mouse wheel from affecting things in the PropertyManger window?
