I've borrowed this navbar script from Dynamin Drive, and it's working fine and dandy, but I can't vertically position the text. I've got some cells with 2 lines, some with 1 line, and I want all the text to appear horizontaly and vertically in the center.

Sadly, I can install these scripts, and modify them a bit, but as for writing var's and stuff, I haven't got a clue. Any help would be appreciated.
