I got your emails in spam folder but maybe here will be better to awswer so:
- current public MorphOS RDesktop version is based on RDesktop 1.8 sources, so it is pretty uptodate but it lacks error window (so in fact nothing is shown in case of failure)

- upcomming MorphOS RDesktop version is based on the latest git sources and it will be even more uptodate and will have error handling window.

Most issues currently with any versions came from lack of NLA handling, the best way now is to turn it off on Mindows machine, as we can't use Kerberos.

I'll sent you updated version to check.
