Same issue for me. The HTML file is perfect but the SWF still has the lines between the individual letters. I've tried all of the suggestion in this and the other post I reference. Also, scrolling in FMR gives those redraw lines (I think that's what you call them...) Faint greyish, vertical lines when scrolling. Really annoying! I love Cp but this issue seems to have gone unresolved for some time. Note this: http://forums.adobe.com/thread/830472
I hope I'm missing something but I've run into this in Cp5 and Cp6.
