Thats good, it was just the losing of settings on restart is a very common problem with the papa fabio and other pirate versions.
Your rev however is extremely old and it might be best if you update to a newer version, but thats up to you, some people like the old versions. If you do update I suggest you copy the entire Mach3 folder to a different location on your drive before you upgrade, that way if anything is lost during the upgrade then you will have a complete backup.
