Clicks in tagline are off by about 1 character

[driusan]

For some reason, since 324f689 clicks in the tagline seem to be off by about 2 character. The imagemap doesn't seem to be calculating correctly, despite being the exact same image map calculator used in the main window, where it works.

It doesn't make it unusable since it seems to be exactly 1 character off, but it's annoying.
