PDF document has rotated automatically 180° DT3

In Devon Think 3 (current update), pages and whole documents are displayed upside down (180°). So far, I have seen this phenomenon when the pages are automatically grouped as they were in the previous session, when Mission Control is used, or when the PDF is simply displayed in full screen mode. It has also happened that a single page in a PDF document has rotated automatically. Would be nice if this is fixed. Thanks a lot
