I found related tickets but nothing for 2.5 directly on point.
If I try to close the "write post" window, I get a popup asking:
"Are you sure you want to navigate away from this page?
The changes you made will be lost if you navigate away from this page.
Press okay to continue or cancel to stay on the current page."
This did not occur in WP 2.3. I use Mozilla on OS 10.2.8 on a Mac G4.
I got this error repeatedly even though I had not changed the page since last doing a manual save. It had been idle for hours. I am guessing that the auto-save reset it to be marked as edited.
As a test, I did another manual save and closed the window. It closed promptly without the popup warning.
This sounds like a useful feature that merely needs some tweaking to avoid false positives.
Thanks.
