Whenever I close a document or spreadsheet with LibreOffice sometimes it crashes or turns the screen into the desktop image(without the sidebar) and hangs there for a few seconds before restoring or sometimes it crashes the document image and I can’t return to the desktop or navigate to other programs (e.g. Firefox). It’s happened quite frequently now and becoming a nuisance. Is there a quick fix for this?
I’m using Ubuntu 12.04 (32bit)
