Fixed Add text and Note in the PDF editor closing their text box as soon as it opened.
Exporting to Secure Files now shows Open Secure Files when the PDF is ready. Some browsers blocked the new tab after a long export and opened Secure Files in place of the editor instead.
Also fixed: a highlight could be added to another page if you moved to another page while it was being placed; Undo named a dragged page incorrectly, and a drag that changed nothing added an Undo step; a page image that could not be drawn showed as a broken image. Files handed between pages and editor sessions are now removed from the browser once they expire, the next time you open PDF Workspace, Secure Files or Your images.
