quick launch icon size

Can anyone tell me a way to change the size of the quick launch and taskbar icons on Windows XP, I want to enlarge it, so how to do that? Thanks.

I think that you can simply right click on the quick launch and then select view and then large, that will do that.

Thanks for that, it worked fine for me. I needed to uncheck the "Lock the taskbar" to get the handle for the launch area and then right click on that gave me view and then large icons option.
