Hi. I've created an eBook conversion using Calibre which I find came out quite good (took me around a dozen attempts with lots of tweaking of my Word doc). I used Word 2010 > Web Page > MOBI. My question is this; when I converted the Web Page to Mobi the circles I placed around certain words and symbols on my screen shots moved.

Is there some way to lock such objects in place?

Thanks!
