Excel 2013 Opening Size of Sheet

First, I always close sheets in the position and size that I want them to open in.

However, with my new Office 2013, when I open a sheet, or even first open Excel and it comes up with a new sheet, it's opens in a small window and the window is positioned in the left lower quadrant of my screen, about 2 or 3 inches in from the left and up from the bottom.

If I then grab the title bar and slide the window to the left and off screen, until my cursor is off screen, then the window snaps open to fill half the screen on the left side. BUT, really annoying, if I then open a second sheet it gets opened exactly as the first did, small. It does not matter how many times I slide it left anfd make it snap to the size I want, it still opens new sheets in a small windows.

How do I stop that? How do I force all new sheets, or even the first start of Excel, to open in a window on the left half of the screen?

Didn't work. I opened a sheet and as usual it opened in a small window. I then dragged the edges to make it 1/2 screen size. I then saved it and closed the sheet. When I tried to reopen the sheet it came up in a small window size again.

My anger at Microsoft increases, or at least gets reinforced, every day, multiple times a day, as I need to open and close sheets throughout the day and each time I have to take 4" by 6" window and snap it to 1/2 screen.

Didn't work. Once more I want to smash my screen.

How does one contact those morons at Microsoft to get an answer?
