And I was thinking later on that same memorable day after I had checked the boxes on the left for the umpteenth time and pressed Remove Marked Messages -
Oh, gee, is that what that scroll bar at the bottom of the window is for??
LOL!

But you know, if I didn't maximize the window, I may not have seen the scroll bar to even think of scrolling to the right. I am glad to hear someone heard the cries of help in the distance and came to the rescue. LOL
