Can you figure this out?

I was trying to create a simple form with Word 2007. I placed several
tables on a page and then proceeded to delete a row from the top table.

Oddly enough, this caused another table to jump to the top portion of the
page and it would not be placed back into position. It's the strangest
(stupidest) thing I have ever seen in Word.

It's really hard to explain well without showing it to you, so please take a
look at the video of my problem at http://www.mediafire.com/?bx1svd4zzjp and
let me know if you have a solution to this. (The video file is WMV and
about 2.5 Mb.)

Thanks!
