Dials 0 or 100, nothing in between

Hello!  I'm guessing this is maybe an easy fix, but I haven't been able to find an answer searching through the knowledge base and forums. 
We are using Hog4pc, with a wing, and have had no issues for many years.  Now, when we turn an encoder, either on the wing or on the virtual wing on the screen, the values jump all the way to the highest value, or the lowest value.  For example, on a fixture if I try to pan, one "click" of the wheel left will set the value at -127, and one "click" right will set it at 127.  Same with intensity. 0-100, nothing in between.  Encoders for gobos and colors don't seem to be working at all.  

Did we just accidentally turn on a setting or something?  Thanks in advance for any help you can provide!
