Problem originates typically from documents pasted into editor from Word, but the problem is spotty and goes beyond it. Either way, there's issues with the way you'd expect this to behave:
Copy and paste the following code into HTML View:
<begin code block>
<p style="margin-bottom:0in;margin-bottom:.0001pt;line-height: normal"><span style="font-size:10.0pt;font-family:"Comic Sans MS";Times New Roman";Times New Roman";color:#0070C0">Thank you for coming to Parent Teacher Conferences! It was wonderful to speak with you!</span></p>
</end code block>
EXAMPLE:
Thank you for coming to Parent Teacher Conferences! It was wonderful to speak with you!
In the example above:
1) Highlight "Thank" and then bold it
2) Highlight "for" and then bold it
3) Highlight "for" again, and then change the font color to RED by clicking the "font color" icon in the tool bar.
PROBLEM ILLUSTRATED:
Thank you for coming to Parent Teacher Conferences! It was wonderful to speak with you!
PROBLEM EXPLAINED:
1) "for" is bolded, but not red
2) everything after "for" is red
3) only "for" should be bold + red
