<p>System Win 7 Pro  64-bit with PMail v4.63; Firefox browser, v42.0 This is just a reminder note as the query has cropped up before it seems and my problem is now solved! The system had been working fine until I had a <i>"problem"</i> two days ago in the evening.   PMail had been receiving and sending messages normally.   Later in the day downloading some messages they appeared in my New Message window list with some 70+ other messages.  When I clicked on the Open button at the top nothing happened apparently, except for a dotted marquee round the message line.   I tried some other messages in the list which had opened on the days I received them.  I also checked messages in various subject folders I could not open these either.   I searched the forum, but the only two threads were 06-21-2008, 1:56    Barry L "Unable to read down-loaded message after selecting 'open' in 'new mail folder' " 10-29-2014, 3:05       DrPeter "Cannot Open messages"   The first thread cleared up <i>"my problem"</i>.   It was finger trouble - I must have widened the window to display various messages, then closed it up and later found messages were not appearing in the reduced size window!</p><p>Rodney Fry </p><p> </p>
