ok so the freewheel software I have is version 2.2.1, and I don't have a mx1000.driver, I have cocolino.driver, and that is version 1.3c
I haven't seen any problems you describe, BUT closer inspection; I did wipe out my old s:user-startup when I copied over the ApolloOS off of my A600. Looking at a backup of my system from prior to that, (incase the apolloOS copy didn't work out), I can see the cocolino.driver get called to run at the top of my old user-startup - this is of course, missing on my current user-startup.
so. I don't have any problems, because i'm not running it.
ok, at least I got the version information for you. if the massive data copy i'm currently doing over Parnet fails anytime soon, i'll mod the user-startup to include the cocolino driver and see if that still works or not.
