need parallels to have its own desktop

I installed Parraells with Windows yesterday and it was working perfectly. I have a 27" iMac and an external 34" LG. When I installed it Windows was running on its own desktop. I could access the window/desktop by swiping up four fingers and clicking on the desktop. Perfect. I could control my Mac with two screens as always and when I need to get into Windows I just clicked on it.

I had to restart my machine and when it came back, Windows was now controlling the left screen and my Mac was on my right screen.. UGH Now my dock won't come up on the left screen.....Any ideas?
Thanks so much!

 

Hello, are you using your Parallels Desktop VM on the external monitor?
