How to stop text box on iWeb page from automatically reverting to hyperlink when I click 'save'

Question

As far as I see, the main text box in the body section of my iWeb page reverts to a hyperlink (connecting to a file) when I click save.  I don't know how the hyperlink got activated to begin with--I must have done something, but I don't know what it was.  I tried this many times to fix it: went to Inspector "hyperlink" section, activated the text box in the page, un-clicked "make hyperlinks active" (so they are inactive), then un-clicked "Enable as a hyperlink."  That much works--the hyperlink (little white arrow in blue circle) disappears from the lower right corner of text box.  But as soon as I save (command S), the text box reverts to a hyperlink. 
If I don't click save and move around the pages, it does not revert to a hyperlink.  It only reverts to a hyperlink when the file is saved.  Why is it doing this and how to stop this from happening--how to permanently return the text box to a non-hyperlink?
The website page is: http://www.usronline.net/USR/VedicResearch.html.  If you click anywhere randomly in the main text, you'll get a prompt to download a PDF file.  This should not be, but I can't get this hyperlink to go away for good.
Many thanks in advance.

Please pardon the reply delay--a big project deadline had to be met.  Now back to this work:
Yes, the text in the oval object had a drop shadow (the oval object itself did not).  I removed the drop shadow from the text, but the image file icon stayed in the right corner of the oval object.  I deleted the text and then the image file icon disappeared.  But as soon as I typed text again inside the oval object (not even pasting the previous text) the image file icon appeared again.  I deleted the oval object entirely and simply typed the text inside the main text box itself.  The image file icon that was attached to that oval object is gone (along with the oval object).
Still the image file icon is attached to the main text box, though.  I again tried to uncheck the Enable as hyperlink (same process as described in first posting) with that oval object gone, but when I "save" again it reverts to a hyperlink. 
Next I tried this: I copied the text from the problem text box and pasted it into another text box (outside of the problem one).  Still in the new text box with the pasted text, the image file icon shows in the upper right corner. 
I also removed all the drop shadow features from this main text box (there was one more, on some words typed in the main text box), but it is still showing as an image.
I don't know how it became an image file, and I'm still stumped as to how to fix it (short of forgetting about trying to figure out how it became an image and just retyping all text into a new text box).
The link you provided for "Web Safe Fonts" is returning this: "The server at www.ampsoft.net is taking too long to respond."  I'm using Arial and Georgia (Georgia only on the menu and header text) in the site, and I had verified before designing the site that these are web safe, so I had thought they were.
If you or anyone have any further suggestions or suspicions on this matter, I'd be glad to hear them.
Thank you.
