In Slick load some file that will be diffed (e.g C:\temp\foo.txt)
Run a mf DZ with LaunchInSeparateProcess.
Switch to Slick and modify the file, but do not save.
Go back to DZ, open the Diff on that file.
Modify the file, close the diff - saving the file.
Go back to Slick.
Slick does *not* noticed that the file was changed.
From a CMD window, do this:
echo TESTING >> C:\temp\foo.txt
And go back to Slick.
Slick notices and prompts to reload the file.
Seems odd that Slick noticed the change from CMD, but not from DZ.
Note that when DZ saved the file it did update the last-modified timestamp and size.
