Its called under lock yes. The problem with this fix is that we currently have the requirement that the rmap invalidate_all call requires the pagelock to be held. That is not the case here. So I used _begin/_end to skirt the issue. If you do not need the Pagelock to be held (it holds off modifications on the page!) then we are fine. ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
