Thanks for the feedback and glad to hear that you have not had the problem. Since my knowledge of the 970 was limited to the postings on this board, I have no direct knowledge of the percentage of 970's that have the problem. In reading some of the posting's it appeared that sometimes a significant proportion of owners had the issue.

As a result, I been reluctant to bid on 970's, especially when seller's conveyed no knowledge of the problem or refused to respond to my question. I would be less reluctant to buy from those who acknowledged that they had heard of the problem, but either never experienced it or had it go away as the result of a firmware update.
