I to have the same complaint, not only the start screen but also preferences pops up there.
Like Bob once repositioned it should remember where it was last placed.
I realize now that even the Open dialog box can be trained, and will remember from session to session. I've since turned off the Start Screen. My practice has normally been to right click my Taskbar Icon and select a recently used project, so that's still how I will work. Anything further can be found through the Open dialog.
