Got through over 19500 bookmarks, and it froze on the last 2! I left it alone for a good half hour before giving up. Sadly, this process took several hours, and was very resource intensive while running. The process appeared to be fruitful, there were many dead links to remove, but what good is it if it hangs just before completion?
The only known case for such a thing was when bookmarks were added when a bookmarks check was already in progress. That's fixed in Bookmarks Organizer 4.0.
