Open application windows in the same place consistently

Hello,

I am hoping to find out if anyone knows of a good way to convince application windows to open in the same location on the screen every time, consistently. This is, clearly, a minor problem, but perhaps you know how to do it. For example, I tend to use Safari with the window open over the entire screen, but every time I open a new window it locates itself with a couple mm between left side of the screen and left side of the Safari window, and the right side of the Safari window (the scroll bar) is partially off the screen (because the window is shifted). So every time I open a new Safari window I have to click the top bar and drag it a little bit to place it where I want it. Is there a way to "teach" Safari where I want it to open so that it will open in the same place every time? Maybe the problem is that I have a hidden dock on the left side of the screen and Safari does not want to come too close to the dock?

(I also have the same issue with Mail, because though I use that program with the application window only open over part of the total screen area it always opens in the same place on the screen which is always slightly off from where I want it to be)

Any suggestions? Thanks!!
