I'm having issues with post-new.php and page-new.php pages in the wp admin. Whenever I go to either one it only loads so far (stops after loading the image uploader) and then it just hangs for a few seconds until my whole browser freezes and then I have to wait another 1-3 minutes before the page will FINALLY load. These are the only two pages in the whole admin that do this and I'm completely stumped as to why.
What I've checked so far:
-Turned off ALL plugins (separately and all together).
-Tried with and without the visual editor on. With the editor on, it stops short of loading the tinyMCE buttons. Without it on, the quicktags load, though.
-Completely re-installed WP.
-Checked in Firefox, IE and Safari (same problem in all).
-Got other people on other computers to check and they had the same problem.
-Installed ANOTHER wp blog on a subdomain and had the same problem.
I contacted my hosting company (which I use for multiple WP blog across several of their servers and have never encountered this issue) who told me that when these lines were commented out of post-new.php, they were able to get the page to load fine:
However, when I tried I still had the same issue, plus disabling those make the editor not work correctly, so that's not a good solution even if it did fix the page load problem.
So I'm completely and utterly stumped. Can someone shed some light on this?
My host seems to think it's a WP bug, but since WP works fine on their other servers it seems to me that it's a server issue. They're stumped as well, though, and won't really look into it more since they think it's an issue with WP and not them.

Any help would be appreciated.
