I'm a bit curious about this -- it seems that in the AutoCAD Style dialog, and in no other application I've used, there are duplicate font names, with a @ symbol prefacing the name fo many TTF fonts and moving that entry to the top of the list. It doesn't happen to every font, but the list of affected font names seems to grow over time, and differs between computers.

for example, The Windows font folder shows a "Batang Regular" font, while AutoCAD shows both a "@BATANG" and a "BATANG" font. None of the impacted fonts are one I recall ever using.

Anyone know why this happens?
