Named anchor jump problem

Hi all,

First post here, so the usual new user apologies-in-advance apply.

There's an odd problem I'm experiencing with Firefox (1.5.x for Mac and Windows) and Safari (any version, I think, for Mac). Rather than exerting an inordinate amount of effort writing down what the problem is, I'll just show you:

1. Be so kind as to visit http://www.bettertrolley.com/index_sep06.html in Firefox or Safari.
2. Here's the site. You'll be presented with a transit map on the left, and a column information on the right. Click on any station (that is, any of the items in black type) on the transit map.
3. What's supposed to happen is the area under "Station Information" changes to what station you clicked.

Now -- here's the problem. If your viewport was set to something 1024 x 768-ish or smaller, you'll have noticed it already: the page "jumps" down.

I can explain partly why this happens, I think: The station information list is a big long page (http://www.bettertrolley.com/maps/stations.xml) inside of an iframe with lots of named anchors (#1, #2, #3 ... #53). So what the Flash module does is get a URL like "stations.xml#25" with the target being the iframe. The browser tries to scroll the parent window along with the child (iframe) window when the link is clicked to go the named anchor.

Whew.

So how might I solve this? How can I get the iframe to jump to the right location, but not have the parent window try to jump there too? (Oddly enough, IE 6 for Windows does this properly. I know. I was as stunned as you are.)

Thanks in advance for your help. Any suggestions will be greatly appreciated.

(edit: I had a typo in one of my URLs.)
