In regards to 'tripling', it sounds like the material/image needs stretching into place. (probably not the right term). But anyway, drag the middle mouse button inside the uv editor circle. Drag up or sideways to check the different affects.
For resetting, double click inside the uv circle. The Texture Coordinate Parameters box will appear, and you'll see a button there that says 'Reset to default'.
EDIT: Sorry. First select the offending face, then the UV button/tool. then double click.
One thing i can
highly recommend for us 'oldies' is to Print the manual, and put it into a clearfile. (one which you can add extra clear pages to.)
You'll probably understand when i say, "you can't beat a book"
Which is not to say that the internet is inferior. As you know, the internet is an
Amazing information resource, be it forums or other.
But the manual, in good old hard copy style, i found essential to my learning process.
In fact, i still print anything i find important, or worth keeping.
Best of wishes for your endeavours.
