Application not responding : how to save data before I force quit?

Hi,

I have an application (Liquid Ledger) that's not responding.
The spinning wheel has been going for ages and the program is stuck.
I've got lots of un-saved data in the document that's open (stupid, I know!)

Is there a way to save the document before I force quit the program?

I think in word any unsaved data goes into a temp file, will there be a temp file with my Liquid Ledger document data and how do I find it?

Many Thanks for any help,
Cal
