Bug?? HogPC v3 vs. v4 Programming Wing Not Working

FYI
I recently installed Hog 4PC with Hog 3PC concurrently installed and no longer had functionality of my programming wing in Hog 3PC. I did several reinstalls of Hog3PC to no avail. It was only after I did a system restore to take Hog 4PC off the machine (not an uninstall of just Hog 4PC but to the same effect). Wing now works fine with Hog 3PC.

Anyone else see this/replicate this?


System:
Windows 7
Gateway 21.5 all in one touchscreen computer running as client to a remote server.
