This font rendering issue is no doubt related.It may be caused by Windows. Here's an interesting pic: http://stackoverflow.com/questions/190344/wpf-blurry-fonts-problem-solutions (Look for the "cascade" pic in the top answer.) When we have truly hi-res monitors, ClearType and WPF will solve the kinds of problems you see in Reader. (Unless it truly is an Adobe thing!) Cheers, Nick.
That would be great--but until the resolution of the monitor exceeds the resolution of my eyes, there will always be some quantization effects--with antialiasing (blurring) required to paper over them. The curious thing about this effect is its discrete nature and its selective effects--the inequalities only appear at specific sizes and to specific ranges of letters (not shapes or sizes of letters). The difference is not subtle--it's at least a 10% variation in point size. I'm running Vista on this machine, and I thought that font antialiasing was the default setting. Maybe an application can override the default. I've only noticed this effect in Reader, but it's also the easiest app to vary font scaling continuously. -michael NadaNet 3.1 for Apple II parallel computing!
