Urgent help! InDesign won't save my project!
I have been working on a project now all day, and when I went to save it, it comes up as this:

The "save menu" is non existent, and there's nowhere for me to click anything. I've tried save, save as, export, all brings me the same thing. If I try and exit out of the application, it asks me to save and I click that. It brings this same menu up! I assume this is a glitch that my application is not working correctly?? If I force quit, will I lose all my work???? Has anyone else experienced this?? I work on a Mac. Help please!
