Hi,

I've been consistantly seeing an appcrash for calibre-parallel.exe in Windows Reliability History whenever I close out an ePub while using the Calibre Reader over the past several versions of Calibre 4 (I'm on 4.16 as of now).

This is no big deal since it's not doing any harm, and the app itself isn't crashing, but I was still curious if anyone happens to know what could be going on or provide some guidance. Thannks in advance!
