I recently started using this library to do some quick PDF exporting procedures (which this has been great for - thanks for the great library!), and while working with it, I've stumbled across a bit of strange behavior:
While running some preliminary tests, I was having crashes when I attempted to save PDFs - or, more specifically, every subsequent time I tried to save. The first time I ran the application, things would work fine, but then when I tried to export the PDF again using the same filename in a future session, the application would crash with an exception saying "The process cannot access the file "..." because it is being used by another process".
Upon further investigation, I've come to realize that the issue was caused by having a Windows Explorer window open with a preview pane viewing the file. When I click away from that document, the issue goes away.
At this point I don't know whether this qualifies as a bug exactly - it's entirely possible that there is no way to identify that it is Windows Explorer using the file rather than some other process - so sorry if I've posted this in the wrong place. But I felt it was worth bringing to your attention regardless.
