This problem has been fixed in
Release 2, which is now available for download (Version 4 users download
Release 4). Meanwhile, note that this problem is directly related to the previous question in that, when attempting to fix it, your "extra" spaces will often disappear into the hidden text. Until you get release 2, click on Show/Hide, position the cursor immediately before (or after, whichever the case may be) the hidden content, enter your lost space, then click on Show/Hide to put things back to "normal."
