You know, I thought that was the case as well but I could SWEAR I saw a circumstance where there was NO attachment and was STILL dark-grey-highlighted. I do not exactly recall the circumstance surrounding the email where I THOUGHT it was highlighted but with NO attachment but vaguely remember that there were graphics and an email in HTML format. Perhaps K9 is "confused" about indicating an email with an attachment when it might have some specific types of HTML code triggering the dark-grey highlight??
I'm still not sure. Anyone else have any ideas??
And another thing...the app is GREAT in that there are some many settings and adjustment, however, there are SO MANY SETTINGS AND ADJUSTMENT!!! Is there ANY FAQ or manual online whatsoever?? I never saw an app with SO many option yet so LITTLE online or other support. The developer has GOT to have some notes on all the junk in the program, no?? :-))
I JUUUUUST happened to check my K9 email after posting the above reply and can CONFIRM that the dark grey highlighting does NOT MEAN a there is an attachment. I have one ONE highlighted email and it has an attachment but two other emails WITH attachments and NO highlight.
Annnnnnnnd I just checked again...now that I have read the messages, the highlighting is GONE...
So I am still confused...
