Here’s what happens:
Movable Type uses the same name for its textarea on both the Edit Comment page and the Edit Entry page. Both are named “text.� When you view the Edit Comment page to delete a comment, Safari caches the text inside that textarea. Then, immediately after clicking the Delete button, MT forwards you to the comment’s related entry.
This is where the problem starts. Safari loads the cached comment text into the “text� textarea on the Edit Entry page.
I've verified this by viewing the source of a page on which the entry's content was replaced by comment content, and the source does indeed contain the proper content even though the page itself does not. You can view an example here: http://www.maniacalrage.net/archives/2003/...g_reduction.php
If you hit save, you’ll post the text in the actual box to your server, and overwrite your entry.
So the problem is Safari. And it’s a cache problem. I’ve reported a bug to Apple, trackbacked an entry to Dave Hyatt, so hopefully at least someone will fix this in the long run. In the meantime, just be careful if you’re a Safari/MT user.
