Embedded fonts in comboBox component

Hi all,

I know this has been discussed many times, and I've tried every fix ever posted anywhere and no joy... I've managed to embed my fonts (using _global.style.setStyle) so they appear correctly in the comboBox dropdown. However, the text at the top (the selected text) doesn't display. If I don't embed the fonts, it all works correctly. I am using a mask, which I've applied using setMask() but even if I remove it it doesn't change anything, so it's not that which is breaking it. I've tried embedding the fonts for the instance only (using this.setStyle()), I've tried creating a new mx.styles.CSSStyleDeclaration(); and applying them that way, still the same thing keeps happening.

Does anybody know why this is happening? I'm going nuts here, styling and skinning a few simple comboBoxes has taken me longer than if I were to write them from scratch...

Thanks a lot,
Caro.
