AnFX Version 6.0.4.1 allows configuration of text quality parameters that cause a change in the quality of the text output from the Flash player.

For both single line and multi line text actor types the user can specify a 'movie' wide option for each type.

You access these options by right clicking on the stage window on empty space and choosing "Produciton properties..."

The options are:

Text Rendering Engine: Normal or Advanced

Grid Fit Algorithm: none, pixel, subpixel.
