File is marked with an asterisk right after opening it.

Hi Rob, thank you for your answer. I know what you're talking about, I've noticed that in the past when I opened excisting files with the newest version of the software. But this is different, it has nothing to do with files created with an older version and being opened for the first time with a newer version.

Let me explain in more detail what I'm encountering.

I open an excisting file which I've made with the previous version, like always it opens with an asterisk because it's the first time being opened in a newer version. I give the command <save> and get the window where I can determine where I want the file to be saved, I save the file and the asterisk is gone. I make the changes needed to the file, and off course right after the first change the asterisk shows up again, when I give the command <save as> to save the changed file under a new name the window comes up so I can change the name of the file and save it on a new location. So far nothing out of the ordenary. I close the file because I'm done working on it. I don't shut down InDesign, I just close the file.

Now when I open the file to which I've just made the changes and which I saved under a new name, again it shows the asterisk right after opening, no changes made to it yet.

Even after I shut down InDesign and open the file after navigating to it in Finder, so InDesign has to start up before opening the file, the asterisk shows up right after opening.

It doesn't effect my work or compromise the file whatsoever, I just like to know why this happens, because not understanding bugs me hahaha. I never encountered this in the past, besides opening files made with the older version for the first time in the newer version of InDesign.

Oh by the way, sorry if the grammar in my text isn't what it needs to be here and there. I'm Dutch and speaking English is no problem whatsoever for me but me writing it will probably leave room for improvement.

Thank you for your patience, time and expertise,

Marc
