On a desktop, everything works fine. On my Android, I cannot easily close this window. It should be possible to close it by clicking...

...the "X" in the top right,

...the "close" link at the bottom

...anywhere outside this faux-window.

On Android, it is possible to close the window under the following circumstances:

If I don't scroll at all, and click the "X" in the top right, it *sometimes* works.

If I click below the "X" enough so that I'm clicking closer to "about", it works. This has something to do with the fact that I made the clickable area of the "X" much larger than the "X" itself (80x80 pixels)

If I click near the bottom "close" link like a madman, it works maybe 1 out of 50 times.
