Scans Bookmarks well but when finished it just stops - no indication it is done. It places a red X on each bad bookmark in your bookmark tree display but makes no effort to create another Bad Bookmark List for your editing or deleting. Each and every bad bookmark must be handled individually - no batch or group delete function. Also, if you attempt to simply delete a Bookmark Folder in the tree display, the program faults with an Unhandled Exception Error. Lastly, there is no way to Save your Scan so you can come back later and make your edits/deletions. This forces you to make your edits all at one time or loose your Scan (forces you to Re-Scan) which might be a very lengthly process if you have a lot of saved bookmarks.
