Hi, I am using Xournal and I really like it. However, everytime when I try to exit the program, there will be message saying 'error saving file autosave' even I have just saved the file manually or not. Is there any cure for this issue. Besides, I download this software using the App Magr. with N900, is this the latest version? If not where can I get the latest one, thanks again for your work.
