soooo laggy!!!! ALL I WANT TO DO IS DELETE 4000 PRIMS!!!!

hahaha!! so trying to remove the lag by deleting 4000 ish scripted prims! sounds like fun desnt it!! well... its not... the first selection goes fast to remove but after that there is a huge delay in the system and it doesn't delete them for several minutes.... well it doesnt register their absence for several minutes that is!!

heres a pic of me waiting with lts selected..
as you can see its currently only registered 6 prims even though there are probly several thousand selected
hmmm!!!
