Thanks so much for letting me know the status had changed back again Bill. I am so relieved. I fixed a number of links that had become outdated and were redirecting to advertising sites. One I removed was still actually valid but was generating a popup that had red status. This was probably the one that caused the problem. Even though the website itself was still valid I removed it rather than scare people away by making it look like I was linking to suspect sites.

I really appreciate being notified about this. It could easily happen again in the future but if I am let know then I can try to eliminate it as quickly as possible.
