Inphektion to answer your question, I was using BBSpell on the 8700 without any issues. When I upgraded to an 8800, I naturally wanted to use the same product I had used previously. Not to mention that I had purchased a license for BBSpell, and I want to get my $'s worth.
In addition, the "Autocheck" feature for this new version looked very attractive on paper. In practice, it does not work a LOT of the time.
To be fair, BBSpell works well on the 8800 if you disable the "autocheck" feature (which, by the way is the default setting).
I'd love to see this feature get fixed in the official release. Either that, or Somedevelopers should kill it entirely. I have some other suggestions for them that may alleviate or at least obfuscate some of the issues they are encountering, if they would reach out to me, but they are probably too busy trying to make their product work...
After my license runs out, I will re-evaluate using them again, given their lack of support.
