yep... when I get this problem I defrag.. and it takes a looong time on a 80GB HD, and I still have to delete something.. nothing much, but still something... and its terrible cause sometimes you dont have the time to do that or what to delete! So I think I will put everything on the same drive.. do all the above! whatever the case.. I will still have 30GB free... If it doesnt help I will try he hammer therapy! As I am a victim with all kinds of problems.. if it works here it will work anywhere and I will let you guys know.. Tomorrow I will have if formated, so everybody cross your fingers and toes... and again.. as queri said.. only happens in a new window... but.. I did nothin since yesterday and today it was rendering.. so it may be the temp as someone mentioned... so I need more temp space right? which means more HD space.. so 30GB would at least help???
