You dont have the font file loaded, so it automatically generates a font for you. Go to Config | Font and then reload the anex86.bmp file. This happens if you move the Anex86 files to a different folder.
The blocky version of the font can be reproduced by selecting Default from the autogenerate box. Since your default font isn't "wide" it generates a blocky text. The bmp is always the better option though.
