I was just editing the following wikipage http://wiserearth.org/article/63f44f3c4e7891627c0ed210ddf12f71 and encounter some anomalies:
1. My edits were saved, but upon logging out of WiserEarth and logging back in to view that page, the edits were gone and the page revert back to previous version.
2. This happened several times.
3. Now, the revision number is 19, but when I clicked on "Show History", there are double entries for each revision number. In other words, the total is 19 revisions, but in the list, the largest number was 10. Please have a look at the page to see what I mean.
4. While doing the editing, it seems that I was logged out involuntarily from WiserEarth... is it my browser's mistake? and is this the cause of or related to the above anomalies in any way?

I'm on Netscape Navigator 9.0.0.5 (based on Firefox 2.0.0.11) in Win XP Pro SP2.
