When saving in Adobe After Effects I sometimes get this result...

I'm saving my project as an aep file so I can have it for future editing. Sometimes Adobe will kick me back to the original directory and insist I save it as an untitled project. If I try to save it anywhere else and give it any other name than the default of untitled, After effects will automatically kick me back to the original directory I was in when I started my project and revert the name back to the default of UNTITLED. What I have to do then is accept the defaults, close After Effects, manually move the aep file to where I want it with my mouse and rename it using Windows (right-click - RENAME). Doesn't always happen but whewn it does this is the only apparent fix. Any bright ideas? Be nice if I could do a video capture, however I can't make it happen, it does this at random. Thank you.
