In IE11 if the viewer is opened several times in a session an “Out of memory” error occurs.
Note: The version used is @pdftron/pdfjs-express" is “7.3.2”
Can you explain what you mean by “viewer is opened several times in a session”?
Does this mean you are loading PDF.js Express multiple times?
Thanks for following up. Yes, our tester was using IE11 and opened several documents in PDF.js Express. Each time he would click a link from our website and then the PDF.js Express application would initialise and load the document. We have a standard client server website so each page reloads in the browser. It is surprising that there could be a memory issue even with a page reload. Maybe there are items stored in the browser local storage.
