I noticed tonight when I searched that the found threads were not completely in ascending date order by last post. The majority were in that order, but a few (maybe 10%) of the threads with the most recent activity were scattered throughout the rest of the list. I didn't look to see if recent threads were also scattered in the hits listed on other than the first page.
Not a huge concern, but if in looking through the "programming" for other reasons you happen to see why that is occurring and it has an easy fix, that would be appreciated.
(FYI I'm using IE v. 6.0.2900 and XP SP 2)
