query_post & more tag conflict

I try to modify my index, so instead it load the latest post, it load like this:

———
page 1
page 2
page 3
page 4
category 1
———

I use query_post everytime i change the loop, it seems run fine untill i post quite a long post and include “more tag”. This post was filed under category 1, and guess what? the more tag doesn’t work!

After doing some backtrace, i found out that if i use query_post with the post that have more tag included, it won’t work, instead it will show full post.

I’m quite frustated about this one, have anybody try to combine query_post with the post that has more tag? How do you solve this one?

Also how do i revert the back the original sql before i apply the query_post? I notice that if i use that once, the default query is overwriten.

Thank you
