Many (but not quite all) of the outlines of new plant symbols I have created disappear when I make the "none" class invisible, even though the object information tells me they are are in the plants-components-tags class. Centre dots and tags remain visible. Oddly, if I make the "none" class active and switch the visibility to "active class only" they are not visible there either. Where have they gone and how do I get them back? I can get round the problem by always having the "none" class visible but it shouldn't be like this. I've also had problems with off-centre dots but that's a different story. I had these problems with the student version of 2008. Having recently bought the full version I thought I'd start from scratch and avoid the glitches, but it is happening all over again. Any advice gratefully received!
