Text as Links

Hi, this is my first post so bare with me! Only just started to learn how to use flash but am struggling already. Have decent knowledge of css and html though.

I am trying to make simple text buttons however after I have converted it to a button it is only clickable on the actual pixels of the text (using a pixel font also) not the white space between letters. I assume you need to create an area surrounding the text? What’s the best way of doing this?

How do I enable rollovers in flash? Just want the text to change colour when the cursor is over it. I read you could do this with css but I assume this wouldn’t work for pixel fonts which I am using as they would have to be embedded into the flash file. I just want the link/text to change to grey when the cursor hovers over the link.

Any help would be great.
Many Thanks
