I seem to recall this "toolbar horizontal" thing was asked and answered a while back. But I could be wrong.
As for changing preferences, there's no real problem - just make a backup copy of the folder(s) somewhere (stick em on the desktop temporarily, maybe) and if it all goes horribly wrong, then copy 'em back again. And hope that it doesn't b*gg*r up PS in the meantime..
And as for calling yourself "Yourself", etc - yes that
is wrong. Unless you're starting a sentence with it. Or unless your name really
is "Me", or "Myself", etc...
