Finished the book so if you did need me to look at it, that is possible now.
Are you backing up your files as you go forward? If so, you could have just backed up to a previous tlx design file and kept going.
Use FILE SAVE AS every time you open your file. Save the file with a name that includes the date for easiest reference and the files stay in date order too!
-- Example: open main010103 FILE SAVE AS main010203. The next save as: main010303.
-- Subdirectory examples: vacation070103, photos070103 etc.
-- To keep the order correct, use a 6 (010103) or 8 (01012003) digit number - don't use 1-1-03
Simple. Fast. Easy. The publishing information remains the same and is undisturbed. The previous day's file still exists so you can come back to it if necessary and this process creates an unlimited number of backup copies you can delete or archive the old ones as you see fit, or have a record of how your site has progressed.
By the way:
File save as new name with no changes produces an exact replica, same size
File save as new name before page deletions will still be the same size.
File save as new name AFTER page deletions, etc will remove them from the memory of the file and reduce the file size compacting and cleaning the file!
Trudy: You didn't cross your eyes as you entered that letter! That technique I works on our cranky program that does wacky stuff like that!
