Difficult problem to solve, the thing is, you can't know beforehand which style is used in the HTML email (different senders can have different HTML emails) so difficult to "counteract" CSS style conflicts (which most likely is the cause of this problem) once the email is opened in Aware. The best solution I can think of is, try to display the HTML in an iframe because then, there is a "layer" between Aware CSS and the email CSS i.e the email HTML will not affect Aware CSS.
