MacOS – Remember Window Dimension / Position Single Screen Laptop

open only raises a single window:

do shell script "open -a Terminal"

Another way to raise a window is to set its index to 1 and then use AXRaise:

tell application "Terminal"
    set index of window 2 to 1
end tell
tell application "System Events" to tell process "Terminal"
    perform action "AXRaise" of window 1
end tell

I had the same problem since a couple of days. Here's what I've done to (apparently) fix it:

Created another Administrator account. Logged onto that account. Removed DropBox, Skype, Viber, Evernote. Why? Those where the only applications my new account did not run, and my new account never experienced any crashes.

I then got back to my primary account and downloaded the latest version of Skype (7.1) and Viber. I am now running Skype and Viber as before. I had no use for DropBox or Evernote anyway.

I used to have crashes shortly after restarting. I am now on my second hour with a solid machine. I don't know if this will stay so, but at least you can see if it is any help to you.
