The final 8.1 was released with no warning about 8.03 and 8.1 files being incompatible. Bugs reported on the RM forum 1 week before 8.1 was released are still present in 8.1, i.e. they were not fixed. All inexcusable really.
There continues to be very little interaction between RM and all the users reporting bugs and credit to Joe for jumping in to try to investigate the several patterns that appear in the bug reports.
Surely there is now enough reports of issues that RM can implement a professional bug investigation and find a solution, and then implement a proper beta test program and include every single user who reported a problem.
It reminds me of the time that I used to submit a great many bugs to RM, and only once was I contacted for a project file and that was the last I heard about it. The next version of RW was released and the same bug remained unfixed.
