Speech Bubbles tooltip .net Masterpages
I assume you're talking about this script? Can you clarify what you mean by "master pages", for those of us not familiar with the .net platform? In general as long as all components of the script are added to the final output of the page in question, it should work. View source on the pages in question to confirm everything is in place, from the code that goes in the HEAD section of your page, the various references to the .js files and their validity, to the CSS class names that should be assigned to the links in question.
