Hey all...just wanted to let you know that I had reached out to the ModWiggler Disting EX page and sure enough, Mr. Ostler was very quick to respond with a suggested fix which worked perfectly. Was able to update my firmware to 1.9 and now the "V" knob backs out of menus.
In my case a very gentle lever/pry under the knob cab slightly lifted the cap into position (there was a definitive 'slip' upward as I gently lifted it to where you could tell it almost snapped into place).
Very impressed with his responsiveness to my issue...and VERY excited to begin digging in to the Disting EX :)
