That's been my only 'tiny gripe'. I often have DS opened twice, so I can refer back to previous posts when responding. I think that's why my hours logged are off the charts....lol. When I'm done, I close DS, and go on about my business, only to return to see the second DS still connected on my task bar.
I DO miss the ability to peruse the previous posts when responding, because often I'm responding to more than one post, and 9 times out of 10, I can't remember what I was going to say....lol.
