I work on a site with create as the primary edit interface and I use two different machines. Yesterday I made some changes from machine 1, today from machine 2. Now when I enter the edit mode from machine 1, it doesn't take the current page content (which was saved from machine 2), but it replaces the text with the old version that was last saved from this machine.
I can't remember exactly, but this might have something to do with closing the browser when it has unsaved changes. In any case, if create can't auto-detect that its local cached contents are out of date, it should at least ask the user before replacing the current page content with something else, because this makes it of course very easy to accidentally overwrite contents with old versions.
Not sure if this ise related, but I just discovered that if you do the following:
1: go to edit mode
2: change some text
3: click cancel
=> text will revert to its original state
4: click edit again
=> text will change to the version from 3, i.e. the change you discarded by clikcing cancel
P.S.: I just spotted #36, which mentions the notification I suggested in this ticket as well
Another related issue: http://groups.google.com/group/createjs/browse_thread/thread/dd426cba9d1752cd
This will be fixed when we implement #36.
