A commonly expressed problem with Captivate 2 is that text used in transparent captions looks “blurred” or “fuzzy” in published SWFs. This is because of the way “font-smoothing” is applied. You can override this setting, however, by highlighting the text with the highlight color #C0C0C0, as shown [1] here. In Captivate 4, you need only disable the Anti-alias Transparent Captions check box under Edit ~ Preferences ~ Project ~ SWF Size and Quality.
