Make _sans font bold?

Hi all.

In CS3, I could make _sans font bold. For some reason, in CS4 I can’t and I’m not sure why?

I’d like to use _sans so that the device my app runs on will use its native sans-serif font.

To reproduce:
Create text box
Change font to _sans
Try and make font bold

I’m creating a Flash Lite app, so just to ensure it wasn’t to do with that (or the device I’m creating it for) I created a normal Flash AS3.0 document and the bahaviour is exactly the same.

I’ve emailled Adobe but no response. I’ve posted this question in lots of other forums, but no solution! :frowning:
