CONT'D - Board Suggestion
This gets it back over to the left. If multiple responses are being posted to other posts, maybe the poster could put a subtitle in the subject line, i.e.
CONT'D - Board Suggestion-response 2 FrankC (playing with software)
May I suggest an interim solution until Robert can weigh in on this (and I have a feeling nothing can be done).
When a thread is moving off to the right, for your next response, start a new Thread with the same title as the original one with CONT'D at the beginning of the title/subject line.
