Adding quick tags with styles… Error?

Ok this works fine with FF but in IE what should look something like this:
code
<div class=”float”><img src=”http://&#8221; alt=”” /></div>

<div class=”avtitle”>title</div>
code
Looks like this:
code
<div><img src=”http://&#8221; alt=”” /></div>
<div></div>Title
code
After saving.

Most bizarre!

Any clue how to fix it?? I don’t use IE but many of my Authors do…

Thanks again!
