Here is what I experienced when using the TTFs:
It only works when I uncheck the border. when the border is activated there is no text displayed. shadow is working fine.
also the colors are messed up. when a new font is created the color is set to white as standard. but the text in the preview and the game is displayed in cyan.
when I try to adjust a color value the slider jumps automatically all the way to the left and stays there. its stuck so it can't be set anymore.
On a different note:
the dialogs still aren't working in the 4.0 RC mac editor as someone mentioned in this thread:
http://www.visionaire-studio.net/forum/thread/two-mac-errors...hope you guys can fix this as soon as possible. without dialogs it's not the same ;-)
otherwise I love visionaries and the fact that there is now a mac editor!
