I have a week old N810 Diablo. The other day I updated to the latest Xournal....4.2.1. Now it frequently wont load. When it does the icons at bottom don't work.....highlighter doesn't, eraser doesn't, etc and the menus don't open. I have uninstalled and reinstalled twice. Any suggestions? BTW, python 2.5 showed up recently and I don't know why. Is that related and what programs do I need python for? Thanks
