I installed xournal using the install file, and it installed perfectly. Usage is mostly good, it's a great app. PDF reading, anotating and saving works well, and regular journal also works fine. The fullscreen key on my n800 doesn't seem to work though, I have to use
the menu to get fullscreen. But the biggest problem is the frequent crashes that have been reported here by others. It doesn't seem to matter what I am doing in xournal, it will crash after a little bit anyway.
