How would I adjust the width of this? I would like to fill the blank space.

It does by default.
Have you been editing the admin templates?

The default CSS is this:

.xenForm
{
    margin: 10px auto;
    width: 520px;
}

Not that I know of. I try to leave things as stock as possible.

Which template file would that be in?

I found it. this is what mine says.

.xenForm
{
    margin: 10px auto;
    width: @formWidth;
}

Changed it, still the same.

Update: It is fine in IE. The problem is when using FF.

Not an issue.

I think it has to do with browser zoom. try holding ctrl and moving the mouse wheel.
