Photoshop :: Photoshop CS3 A Few Questions

I've just got a job in that requires file names including a full stop
(8.6 for instance). This was never a problem with my old version of Adobe but now, if I save a file like this it then becomes unrecognisable to Adobe when I want to re-open it. Yeeeeeek this is not good.

Second question actually applies to any version of Adobe I've sampled
after my lovely 5.5. When you use CTRL T to free transform, for
instance, you get the litte tabs appear that you can click and drag
for manipulation.

In 5.5 the tabs would appear at the edge of the
file window even if the actual size of the layer was way bigger than
this window. Now they appear around the layer rather than the window
so, as the layer is usually a lot bigger, I have to keep zooming out
of the file just so it becomes small enough within it's window for me
to be able to see and use these tabs. I hope that makes sense -
rather hard to describe. This is driving me mad and I'm wondering if
there is a setting I can use to change this.
