Well, I'm at work (Netscape 4.6, 800 x 600) and I've had another look and guess what? No wiggly "l"s in either regular or bold (unless I look really closely). I still prefer bold, however.
But at work I use my old reading-glasses for screen-work (as advised by my optician), whereas the rest of the time, including using the PC at home, I use varifocals. Putting on the varifocals at work produces the same wiggly effect experienced at home - if anything, it's wigglier here!
