Done probably a whole week now ( Certainly been several days anwyay ) and not had an issue.
Admittedly, I have not undertaken any serious project as of yet, but it has happily compiled a load of junk routines etc without any issues.
The 030 version works perfect on the TT, but has issues on the Falcon, I would sya that its not just lookign for an FPU and an 030 but more specifically tryign to look for something TT specific perhaps, in a kinf od cheap and nasty hacky way to verify that its on a TT?
Either way, the standard version works fine, and so any benefits of using the TT / 030 version of HB is kind of voided through the use of the CT6x
