Actually, I have two different machines, the one with Windows and the other one
with Linux running on it.

You may be right. I can't think how TeXWorks could possibly restore an old
version of the document. Is TeXWorks keeping automatic backups somewhere?
(Like Word and OpenOffice do, to restore a file if they crash)

I'm not sure what you mean. An example what happens:
- I have a file "a.tex" with 600 lines (50kb, don't know if the size matters),
Mercurial-revision: 150. I change something in one line. The file is marked as
changed ("a.tex*" in headline of TeXWorks).
- I save the file ("a.tex" in headline of TeXWorks).
- I switch to hgtk and commit the change, new revision is 151.
- I switch back to TeXWorks. What I see now is the file how it was in revision
150, but still "a.tex" in headline of TeXWorks.
- If I close TeXWorks and reopen it again with my file a.tex then I see the file
from revision 151 again, as it should be. If I don't close the file and change
something else, save and commit again then I destroy the change in revision
So the name is always the same...

I can't answer that for sure. I have trouble with hibernation on my Linux
machine, but I think the problem with messed up documents is older.

I'll try that. Thank you for your help so far.
