WordPress MU

Each time I open this page, the browser scroll bar shows as if this page is 20 - 30 page long, and browser gets frozen. I've disabled all the plugins in use, but it seems this is not caused by plugins.

I've imported another wordpress blog into this new wpmu (eidting is just fine), so I guess import has made some bug on post-new.php file.

another blog running on the same wpmu install without importing is working fine.

ok, this is caused by using import on IE.

Using Firefox or Chrome to import external content will fix this problem.

Are you using a lot of custom fields on the imported post content?
