Flash acts strange sometimes when movie clips, textboxes etc are not on whole pixels. Make sure the textbox has integers for it's coordinates. If it is in any movie clips, make sure those movie clips have integers for coordinates too.
The other option would be to fudge around with the anti-aliasing features in Flash, but that's always a hit-or-miss situation.
