So they actually removed this feature? I was able to right click on a dialog bubble to increase it's size up through last night, but this afternoon nothing happens when I right click. I was wondering if there was some sort of option I might have accidentally toggled to disable this feature, but I guess not.

That's really disappointing. I don't have the greatest vision, so that feature was quite nice to have. I'll probably be just skipping through more dialog now instead of trying to strain to read it.
