Hi,
I've just downloaded and installed TransType Pro 3.0.1 for Windows (trial version).
I'm using the software to fix some naming issues in T1 fonts.
In fact I'm performing a Win T1 --> Win T1 tranformation, editing family names, font name, etc.
The problem is that the resulting pfm files are (all) 1 KB so I suppose I'm losing kerning data in the tranformation...
Of course trial version has some limitations (50% of glyphs are modified and TrT logo is embedded) but this is probably a bug.
What do you think about it?
