Clicking Button to d/l in IE7

Hi guys...

Quck question - a file i want to download is an MP3 on a file storage site. The only option to start the download is to click a button - and then the dowload goes straight to Media player, that is, i don't get the chance to 'save as'. When i right click over the button, i don't get any of the usaul 'right click' option you normally get if you right click over a link. I'm sure that i could find the file in the temp files (maybe?) but would prefer to bring up the 'save as ' option directly as when it goes straight to media player there is inevitablly some other problem, so i'd like to try saving to disc...

So is there an option that when you click on buttons, you can make it go to the 'save as', rather than the file going straight into media player??

I have googled.. but can't seem to get the answer i need.

Thank a lot,
martin
