Have been changing layout and the last thing I did was to make drop down panel for file/edit/view etc and have discovered I have lost the bookmarks name/icon. This was a fresh installation so there were no bookmarks to keep but I can't save any now? Any idea how to get it back, also is there a way of backing up the changes made in the prefs section so if/when I stuff up again I can reload to the last "good" settings.

Thanks
