Soft-hyphens do not work correctly. Image placeholder does not have anyway to access link if image is a hyperlink. The numbers in an ordered list sometimes become part of a link if the text after the number is a link. Last position in a previous document is not saved. Mosaic always goes to the top.
Frames are buggy.
Selection of text is inconsistent. Status messages do not display the correct message or error. Client-side image maps do not work correctly. When downloading a file, the entire path of the file is default, not just the filename. Mosaic will not open a local file with the .htm extention.
