Excel doesn't open window in size last closed

UPDATE**  I found that if I opened additional spreadsheets from within the Excel application they opened at the same size I closed them.  It's only when I open additional spreadsheets directly from a folder that the spreadsheets open at the small size.  Is this a glitch?

I tried this fix, eagerly -- it appeared to be a small glimmer of hope.

Sometimes it seemed to work, other times not.  I could not predict the outcome.

In one instance, the newly opened SS did in fact open to its previously closed size,

BUT

the other SS, already opened, simultaneously changed itself to the same size as the new SS !!!!

Not to mention, of course, that the dialogue box that opens with the FILE command, ALSO opens as a square, meaning that you cannot see all three columns of information without the nuisance of scrolling, or maximizing, at which point the kb shortcuts disappear.

There is no winning with this thing.  Why did they not leave well-enough alone?

Compared to earlier versions, this thing seems to have been created by interns who dropped in over the summer, and certainly not by anyone who actually USES Excel to do real work.

Piece of junk.  Microsoft should be embarrassed by what they have done here.  The shark has been jumped.  It's downhill for them.

In Excel 2007 when I opened a new sheet it opened in a window that was the same size and in same position as the last window I closed. In Excel 2013 every time each new sheet is opened in a small window positioned in the lower left quadrant. I open multiple windows a day and having to resize each one is very time consuming.

I've only ever found one way that works forever to fix this.  So my Excel like everyone's opens in a half window at the top of my monitor viewing area.  I can try to expand the size, but once i get near bottom of monitor 'screen', if you pay close attention you'll see it sort of auto 'fills' to the very top/bottom lines of monitor screen.  You can do whatever you want at that point and it ain't gonna reopen in the desired size, the damage is done.

So for example, I like my Excel to be top-to-bottom but about 1/3 of monitor width real estate.  So first I open any Excel file to the stupid half window.  Then I resize it to maybe 3/4 of the length of the screen up/down.  Now Stop!  Now hold down SHIFT and use the File - Save - Exit commands to close it.

Reopen it.  It should now be in that 3/4 size.  Now resize to the final limit you want.  Make sure to be real careful if/once you get it near bottom so it does not 'auto-fill' (you'll see it maybe slightly resize/shudder a bit if it's doing it).  I'd recommend going with like 95% top-to-bottom size to avoid that, but it can be done to full with a steady hand.  

It's a stupid thing to have to do to an expensive piece of software for something so simple, but that's the ONLY way i've ever found to fix it permanently.
