for some time I have been observing that PDF-XChange Editor crashes after performing the following steps, which admittedly resemble a somewhat advanced workflow of moving pages -- that however can be incredibly useful for large PDF's.
- Grab a PDF with multiple pages and multiple bookmarks, for example the attached e-book
- Activate both Bookmarks and Thumbnails Pane in PDF-XChange Editor
- Select pages 3 and 4 (orange) in the Thumbnails Pane in order to move these pages between pages 8 and 9 (blue)
- Drag the (orange) thumbnails of p. 3 and 4 between the bookmarks "C" and "D" in order to move and insert pages 3 and 4 above page 9
- PDF-XChange Editor will automatically create an empty bookmark named "Untitled" between bookmarks "C" and "D"
- Drag the bookmarks "A" and "B, which are associated with the moved (orange) pages, above or below the "Untitled" bookmark, thus also between bookmarks "C" and "D
- Delete the "Untitled"-Bookmark
Unfortunately this does not seem to happen with the attached PDF, probably this document is too simple in structure. However, it happens to me regularly with longer and larger PDFs.
The issue has been occurring since the awesome feature "drag documents between bookmarks" was introduced (which is still unique in the whole market):

Maybe you can try the above steps on a rather complex and large PDF, and possibly reproduce the crash.
Thanks very much
Kind regards
