Zemanta hangs my wordpress write page every time it updates. Can I set it to only manually update?

In Wordpress 2.5, every time "Save" is clicked on the post drafting page, Zemanta resets to say it will update in 300 characters, no matter how close it was to updating before hitting SAVE. For example, even if Zemanta says it will update in 4 characters immediately before I hit SAVE, after the SAVE it says it will update in 300 characters.

My images appear to be the same immediately before and after the SAVE.. Does Zemanta update as part of the SAVE, or does the behavior I describe mean that Zemanta may bot update for more than 300 characters if SAVE is pressed?

Since I conscientiously SAVE my posts several times while drafting to avoid losing the entire post if I suffer some sort of crash, it would be nice to know that Zemanta is updating upon hitting SAVE. is it? It doesn't appear to. If not, it would be a great improvement. It's too risky to avoid hitting SAVE during mid-draft of a lonng post just to take full advantage of Zemanta.
