I finally determined that I'm not really going goofy... at least not in total.
There have been times in the past where I've "misplaced" various emails, but none of them were big deals. However, the last few days I've been perplexed as to why I couldn't find evidence that I had either sent or saved a long email I was writing to a guy with lots of info on a subject.
I found it today in the "Sent" folder... but it shows in the margin box at the top that it was "never sent"... and shows no date on it as being sent. It should have been in the Draft folder automatically.
Any ideas as to how these dozen or so emails got from the 'Draft' folder to the 'Sent' folder but weren't actually sent to anyone, including myself???
