What's with the ad that keeps popping up when I'm trying to read?

Our web site is hosted for free in exchange for us allowing their ad to appear when the site is first accessed. The key to keeping it from repeatedly popping up is easy.

Do not click on the X in the upper right corner to close the ad window. Just drag the ad window to the lower left corner and it will stay there. As long as their ad window is not closed, you can move anywhere in the site and it will not reappear.

If you click the X to close it, it will reappear as soon as you change pages.
