> What steps will reproduce the problem?
1. Work on an arbitrary map and save it.
2. Exit Xmind with the map still open.
3. Start Xmind again and see: it is marked "modified" (leading asterisk in
the file name tab). 

> What is the expected output? What do you see instead?
I'd expect that Xmind does not touch the file before I actually do something.

> What version of the product are you using? On what operating system?
Xmind 3.0.2 on Windows XP

> Please provide any additional information below.
If you have left Xmind with more than one file open, then only the first
file (leftmost tab) is marked.
