In WebHelp, when I mouse over a link, the font size changes.

Either after I generate to WebHelp or View in RoboHelp, when I mouse over a hyperlink text, the font changes from large to small text. My step is a 11pt font, my body text is 10pt. It appears the 11 pt. font switches to 10pt font when I mouse over it. Any way to fix this?

Also noticed that when I have a note at 9 pt, and mouse over a link, the text changes to 10pt.

So now it appears in most of my topics with links within a step or note. In a body, the text appears fine (or stays the same) when you mouse over a link.
