However, the system obviously notices something goes wrong: if I go in the Apple "Forcequit" menu, shortly after I attempt to open one of the documents, there is the red warning "does not reply" next to Mellel. And the only way to quit Mellel is to forcequit.
Still, there are three Mellel documents which continue to open without any problem on my iBook. This is what really puzzles me: if the problem would be with all Mellel documents - but why are a few exempt from the problem?
As it seems to be a software problem, maybe the content of some Mellel Documents cause Mellel to hang while trying to open a document. The “content” could be a lot of things, for example text/images, text with some fonts, text using some hyphenation-dictionaries, text using some styles/style-sets, text using some auto-title setups (where the images/fonts/styles/auto-title setups/hyphenation-dictionaries could cause your problems)

By the way, since you seem well-informed about that, what are the advantages or inconvenience of having/not having the compressed file format?
In general, the compressed files are a lot of smaller so that’s the suggested option to select. In the past, some users had problems with compressed files, as the used compression library (a part of Mac OS) didn’t work for all users. So I suggested to turn of compression to see if the compression library is the troublemaker.

Neither the age nor the free space guarantees a perfect running system. For example, the HD in my sister’s one year old MacBook died some weeks ago and the first thing she noticed were some Pages documents that refused to open so Pages looked like the bad man at first. As those documents couldn’t be opened on any other system and shortly after some other files couldn’t be opened/saved the real troublemaker became visible. I don’t think that you have the same problem, I only liked to explain, why a faulty HD could make an application look broken.
To solve your problem, you could try three more things.
1. Delete additional files.
The first one was already suggested by Janet & Miles. You could copy all additional Mellel files to a secure place (your desktop, a second HD…) and delete them from your user folder. You’ll find the files here:
Macintosh HD > Users > YourUserName > Library > Preferences >
com.redlex.mellel.plist
This is the preferences file, where your Mellel licence and all Mellel preferences were stored. If your start Mellel after having deleted (moved) this file, you will have to re-enter your license (or use the demo for this test)
Macintosh HD > Users > YourUserName > Library > Application Support >
Mellel
Delete (move) the whole “Mellel” folder (backup first!). This folder contains some auto-save backups, Style-Sets, Auto-Title setups, hyphenation dictionaries and some more files. If you start Mellel after having deleted (moved) this folder, the standard hyphenation dictionaries/style-sets/auto-title setups will automatically be re-created by Mellel. You could delete those and move your old files back, if the problem persists with the new files.
This whole procedure makes Mellel work like it was started the first time (freshly installed). Then you could try to open the documents in question and look if the problem persists or if they would be opened without a hitch. If the latter is the case, you could try to copy one file/folder from your backup back to its original place (the preferences file, the hyphenation dictionaries…) and test a problematic document after each file/folder to track down the buggy file.
If this doesn’t help at all, you could do two more tests.
2. Create a new user.
You could try to create a new user (via System Preferences > Users), log out of your current user account and log into the new one (make sure to copy some buggy Mellel files to a second HD / USB Stick / a folder that is accessible by both users or make the files accessible via your iMac) Then try to open the buggy Mellel files and see what happens. Within the new user account, Mellel behaves like a freshly installed application (the same if you delete the files mentioned above) and also all other applications look like you’ve never started/touched them. Maybe there is some file on your original user account that causes the trouble other than the Mellel files mentioned above.
3. Clean some caches
Mac OS X generates some cache files for various reasons that will be used with every user account. Those cache files could became corrupt (very seldom) and cause some trouble. As switching a user doesn’t delete them, you need to delete them manually (which is harmless as they will be re-created after the following restart of your Mac and therefore the restart make take a minute longer than usual but the files are fine afterwards). You could do this comfortably with some tools like Onyx (free) or Cocktail (shareware). You could get it here:
http://www.titanium.free.fr/pgs2/englis ... tiger.html
You could start the application, enter your password and select the “Cleaning” module afterwards. Then switch to the “Caches” tab, select all 4 options (Application, Font, Kernel, System Caches) and hit the Execute button. After the following necessary restart your caches are cleared and you could try (again) if your Mellel problem (which was an OS X problem in this case) is solved.
Hope this helps.
