Yesterday I was working on a rather complicated email message in the New Scheduled Message window. I switched to a different IE tab to double check something and the New Schedule Message window closed and I had to start over. 2nd Try - 1/2 way through the message and I accidentally clicked outside the window instead of at the beginning of a sentence. Window closed and I lost all of my work. 3rd try, I had placed a html address in the message. At the preview I clicked the link to make sure it worked and the window closed and I lost all of my work.
There is a Next button, a Back Link and an Close/Cancel X at the top right hand part of the screen. There is no usability reason for the window to close without deliberate action from the user. Please fix.
