I don't know which version fixed it (probably a 6.3 one)..........
but I am pleased I no longer have to re-register Metro pretty much every time an unstable plugin decides to crash the app and restarting gave some kind of -54 error and saying something like not be able to write to prefs or something.
6.3's latest version seems VERY stable.
Is it time to move 6.22 build 1 to a higher number?
Afterall the demos are based on higher version numbers.
