Apparently, IE6 throws a royal conniption fit when you attempt to have Flash do anything that involves pointing to an anchor tag on the page.
I tried a number of different methods, from a simple getURL to putting all of my functionality directly into JavaScript, but every time, it blew up. More explicitly, it blew up after the second time it was accessed (so, click one functioned fine, click two functioned fine, click three went haywire).
For the issue I was working on, the workaround was to tell the browser to scroll to a certain point on the page instead of jump to an anchor, but I can imagine that’s not going to be a lasting solution, and certainly not dynamic.
