In the last two weeks it has happened several times that I lost the tail of a long wiki page. I think the page gets truncated when I'm doing a preview. Can it be that some chunked transfer doesn't get completed? It has happened both on sites running MediaWiki and on other wiki websites, so it seems to be browser related rather than server related. Perhaps this is related to Firefox 1.5 or 1.5.0.2? I run Linux. I never had this problem with Mozilla 1.7.8. Any clues?
