When I try to save a file in TextEdit or Pages after a pause between last save, it fails due to that error. "Pages could not save example.pages because its location could not be determined." This just started recently, and is annoying.
I think you are going to have to give the precise steps you took from beginning to end to repeat the issue before anyone can help.
The location of the document “Research Paper” cannot be determined.
You can specify where to save it.
Your still not giving the entire story. Beginning means the beginning, not when you saw the problem. How did you create the file? How did it get it's name?
Since you said it happened in pages, I started pages, created a new file, hit cmd-s - it then popped up a dialog with a place to enter a new filename and choose a location.
If you are using the new Squeeze app then you might see this problem. But only if you used it on your Applications folder. I noticed this being discussed on MacUpdate.
Edit.. just thought I'd pop in the MU page for Squeeze so that you can read about it there: http://www.macupdate.com/info.php/id/33585/squeeze
