My PC has always run Sl fine, no problems whatsoever, untill that is a week before 1.9.0 where i had serious trouble logging in, nothing would ress, not my avatar or the land or anyone else, and on top of that teleporting or even sitting down would instantly crash me.
along comes 1.9.0 and now my login issues are non-existant, as are the crashes.....but it still won't ress most things in-game, which is very puzzling =/
