Print menu resets to default when loading Pantone colour book
Bug - Print menu resets to default when selecting a Pantone colour from any book
This in turn causes print tiling, page size etc. to disappear. Then have to return to print dialogue and set everything back to A3, page tiling etc.
Been persisting with this bug for over 6 months, very annoying.

I think I have the same bug, it does that when I drag a symbol to my page (you can see the print margin jump back from A3 to A4).
