Excel 2007 - Worksheet behaviour

Two queries re Excel 2007

1
When loading Excel from an icon, book1 appears. I then open a file from within Excel, and book1 stays there until I close it. How can I either get Excel to load without a spreadsheet, or close book1 as soon as I open one of my docs?

2
Is there any way I can get my spreadsheets to sit in different spots on the screen - I don't mean Window splitting. I might have one s/s sitting very small in the corner of the screen, another filling most of the rest of the screen, a third just behind and below that one.

The idea is to move very quickly between the 3 with a simple click on a visible bit of the s/s.

Further to that, of course, is that these files should retain their position when I close them without affecting every other Excel doc!

This can be done in Excel on Apple Mac - any way to set this up in 2007?

Help will be gratefully accepted and will alleviate a little of my huge frustration with 2007!

Thanks Paul - for the book1 issue I must have something ticked/unticked which I've yet to find.

For the 2nd prob, Save Workspace won't help as, if I have 2 or more spreadsheets open, they will only sit behind each other, ie I can't drag one away and resize just it - if I resize, they all resize. And if I close all that that new size, Excel opens up like that the next time.

(I'm not sure if Excel 2003 on Windows allows this either, but if you can do it on the Mac, surely it's possible in Windows?)

Any further thoughts will be most welcome!
