Where do you find these versions - 220.127.116.11 and 18.104.22.168? Are they developer versions?
All I can find is "APCC Pro - Public Release Version March 7, 2020 APCC Pro v22.214.171.124".
EDIT: Never mind, I see under Help there is a "Check for updates...". I'm a brand-new user of APCC.
SECOND EDIT: What I found in the manual earlier, and now at home trying firsthand, doesn't work. From v126.96.36.199, the "Check for updates" says "No updates to APCC are available". Why is that?
Also, the APCC window is always on top of all other windows. Can that be changed?
