Settings for PostScript font

[Karin1610]

Hi again!
As I said in the other thread about the distorted small dots I'm doing my font with cubic curves now.
I'm mostly gonna use this font in Corel Draw which has a docker that shows a glyph preview. With my previous font in TrueType format that worked fine. But when I export as PostScript, the preview only shows empty glyphs. Other than that the font seems to work though.
I tried with other PostScript fonts and they display normally, so I must be doing something wrong with my settings in FontCreator. Is there anything in particular that I need to be aware of in the settings when I want to export as PostScript?

Do run the Validator to see if there are outline issues.

I did. There are no issues left but off curve extremes, and some I just can't avoid without messing up the outline too much.
But I also have those in my TrueType font and it never caused any problems.
