Thank you for your post.
Users are not always aware if they have the latest version of FileMaker Pro, or if the problem has been reported. Also, the user may report a problem in an older version that may very well be new in the latest version. It is true that we may not fix a problem in an older version, but I don't want to inhibit people from posting.
I have forwarded your suggestion of sub-forums to Modman, and I'm sure he'll take this under consideration.
