If you ever resize the Downloaded Transactions window, it stops auto sizing based on the screen. I don't recall why I did this, but the issue is, when I use my laptop detached from the external monitor, all the buttons the bottom of the window are hidden and you must minimize the window and open it back up to get them to reappear - and that's a pain!
As you can see from the picture, the window is larger than normal. Manually resizing the window to the "normal" size does not work and trying to double click on the resizing bar also does not work.
