icon mode triggers scipt error

I'm using Drupal 4.3.2. Installed 4.3.0 glossary and 4.3.0 nicelinks. IE 6.0.x.

Everything seems to work fine if I have superscripts selected, but if I choose icons, I get script errors and no 'popup' description. I don't get errors for the same page for other nice links (add comment, admin etc), though once I get an error for a glossary term, they won't work either.

(If I didn't have to support NS 4.x as well, I wouldn't have to get images working, darn!).

The errors are:

Line 147 Char 5 Error: 'w' is undefined Code 0 - repeated many times
Line 161 Char 9 Error: Invalid Argument Code 0 - last error, once only

Thanks for a great plugin!
