A very quick trial of aprx v2.08 was concluded in less than 24 hours.
No matter what I did, I could not get it to digit in other than “direct only” mode.
This problem has been discussed online since v2.08’s release three months ago and since it seriously cripples most configurations, I must assume that the package is essentially unsupported.
With the choice of either running an older version which does not have this defect, or dropping it because it is unsupported, the latter wins.
The defect might be fixed in time, but dropping the ball on support will take a long time to live down.
