Thanks for the response.

I reinstalled KOR and once again have access to the files on the 840.

Will try the Library to see if that opens KOR.

Yes, WD has that option to exclude files and I will need to set it up. Would love to know what is triggering the malware warning, though!

So far, so (fairly) good reading both ePub and Mobi. Very inconsistent issues arise such as an occasional blank page that may or may not reappear with the missing text, blank pages with lines (usually part of the contents page) that will usually correct itself, occasional slow page changes.

Overall it works "Fairly" well.

Keeping in mind that I will be using this only for ePub and Mobi book reading, should I leave well enough alone with 5.4, redo with 4.4, or wait it out for the next software update that may (or may not) correct these reading issues.

If I do switch to 4.4, can I stay with the 840 reader or is Coolreader? the preferred option?

Also where do I find the step by step instructions for switching to 4.4 as I have already d/l that software from the Pocketbook site.

Thanks in advance.

PS: For anyone who wants to read from the 840 in either portrait or landscape mode hands free while it stands up, I am using my original Nook HD+ swivel cover! The 840 fits in the plastic internal swivel portion as snugly as if it were designed (width wise) for it. Of course there is vertical space left over so you can either center it, place it at the bottom, or at the top and it will stay securely in place. If you center it or place it at the bottom, you have full access to the on/off button and the cap for the usb and sd card.
