Do they also show up as modified in the commit dialog?

That depends on the application with which you open the files. Some
applications modify every file when opening, writing some "last viewed"
or "last opened" date string to the files.
If you have such applications: get rid of those. It's a clear indication
that the developers of those apps don't use version control - and I
don't think I have to tell you what that means for the quality of those
apps.
