I guess it may be a temporary mistake, but this site just got in last month. At that time I had all static pages, but switched to dynamic just before last months crawl. Googlebot would not touch any dynamic urls and now the only pages indexed are home, about us, links, add link, etc... Only the static pages.
So I just checked it with toolbar to see if the previous pr3 had dropped and it was at pr5!
Is this a normal occurance during update?
