Hi,
There has been a recent update. IF you were to copy and paste to make a backup, the result would be automatically numbered a mach4mill 2. If you see a notification that an update is available, (which by the way I just did) then go ahead and hit orange triangle or green icon to get the current one. Then use Visual Studio app to inspect the header info. Pick the instance and push the "edit" ( pencil ). The most recent update is dated Sept 3 2024. Ver 44143, I have deleted the older.
Get back with your findings.
Hope it is of use.
Chris
