Suddenly, I've been unable to open and view .jpeg files I attach to outgoing emails. I can view .jpeg pics when opened from the desktop, but the same picture when attached to an email, will not open. Instead, I get a new generic "page" icon on the desktop which has a string of undecipherable numbers and letter followed by the designation ".jpg.part"; this icon does nothing when I click on it. Can anyone help me understand what's happening and how it can be remedied?
