Hi John:
Judging from your postings, I think you’re a reasonable man but in this case I don’t think it’s fair to describe your situation as a “vendor related issue”. Naturally, as a dealer, my viewpoint will be different from yours. But there are so many different operating environments: Windows XP, Vista, 7, 8 and server environments (Windows, Linux even some Novell) plus Terminal Services, Citrix and so on. There are certainly many successful Adagio implementations on Terminal Services. However there are sometimes going to be issues where support from an external, experienced dealer like Doug is necessary (there's my bias as adealer showing up). I also support another well-known accounting product and can say that there are even more frequent “challenges” with the operating environment there.
Having said that, I’m happy that you have a new plan of action in which you have confidence. It would be valuable to hear the results at the end.
