Well sure it still anti-aliases.
With pixel fonts, there are two kinds. Photoshop and Flash types.
With Photoshop, most of these are not true pixel fonts, so when in Flash, they appear distorted because with Flash pixel fonts they need to lie directly on a pixel otherwise they anti-alias.
What you need to do is get a font that was made for Flash, then use that, but if your textbox has to be at just the right X and Y coordinates so that the pixels of the text lie on pixels on the stage, usually you have to open the properties of the textbox itself and change the X and Y textboxes to be whole numbers and not decimals. I have experienced it where my text was on whole numbers and it was still distorted (because of the alignment of the text I am supposing) so in this case I just adjust the X and/or Y position by 1 decimal point until it was fixed.
