Dynamic textfield changing the size of my html

Right in the middle of a big project I’ve encounter this problem!!!

I have a number of mc’s that are brough into the main time line script with “attachMovie”.

Each one of these mc’s contain a dynamic text field with a scrollbar component with a scripting that brings in an external html file as well as a css file for the formatting.

I have “verdana” as my embedded font.

As I select different buttons from the menu each page shows up as is should, HOWEVER: the text within the dynamic text field changes size i.e. like a zoom, or a magnifying glass.

Anybody have any idea(s) on how to keep the displayed text from enlarging???
