[TxMt] Troubleshooting Highlighting Preferences

Hello,

HELP! I have recently had to re-enter my registration key in another version of Textmate on my MAC laptop.

But now when I edit (in LaTeX but this problem is independent of the bundle), instead of Textmate automatically highlighting a single, entire line (under preferences), Textmate only underlines the current line according to the chosen highlight color. The cursor marker is also visible, as a blinking underscore. How can I reset to the my earlier setting where the actual line is completely highlighted? I have tried all color and theme combinations.

Thanks a lot,

Matthew
