Help diagnosing multiple exceptions

Hi.

We are currently using PDFNet 6.4.1.29791. We use the WPF control for displaying documents, and I’ve been observing lots of exceptions, so I thought I’ll bundle them, and see if anyone can help pin point their root cause …

pdftron.Common.PDFNetException was unhandled by user code
HResult=-2146233088
Message=Exception:

Hi, the first thing to do would be to try the latest version of PDFNet.

Both the official and nightly release.
Latest official: https://www.pdftron.com/pdfnet/downloads.html
Release channel: http://www.pdftron.com/nightly/?p=stable/

Otherwise, we would need additional information on the steps to reproduce. In particular, if this occurs in the SDK samples, or only in your own project.

Finally, do these errors occur only with certain PDF files, or is it a general issue?
