[Plugin: W3 Total Cache] w3 total cache cache my admin page?

when i writing a new post (probably 30-60 minutes), and i want to schedule it, after click schedule, it publish the post.

i have to flush the cache and schedule again, then only work.

when after i scheduled, i went to see all post, my scheduled post should be in scheduled but not in draft or published status.

i had to flush the cache 2-3x to get it works.

w3 total cache has no update since november 2011, where is the author?

are you going to keep maintaining it? please fix the issue arose in wp 3.4.1.

thanks
