Neanderthal

I'll see if I can explain it better. My page consist of a large table where I have coins listed. I made made a popup the shows the coin in greater detail and there is where question lies. If I click on the coin, my new window appears, but the main page returns to the top of the page, meaning you must scroll back down the page to get to where you were. I know close to nothing about writing code of any type, so I'm a definate noob. I'm using Frontpage to put this site together. I hope that explaination is more clear. The broswer I use is Maxthon.

I would like for my webpage to remain at the point where a link was clicked instead of returning to the top of the page. What codes do I need to add?
