I’ve written quite a few books with LO Writer, and never had this problem until upgrading to Version 7. I use custom titled bookmarks as I’m working on a manuscript, so that I can easily bounce back and forth between sections. All of a sudden, none of them can be deleted. I’ve tried it from the shortcut on the toolbar and the bookmark file from the Insert menu, but the same dialogue box always pops up, and the option of DELETE remains grayed out. This is a problem for submitting a finished draft because anything like that left resident in a manuscript causes conversion problems for the publisher. Most of them prefer a .doc (Windows 97-2003) document file so that is what I primarily use. I’m unsure what happened, but I desperately need a solution on how to make bookmarks removable again.
