Some crashes with FTX Viewer

My client have some problems with using a font I have created and the software FTX Viewer. I have joined some screenshot and I don’t know where is the probblem with my font. If someone could help me…it would be great.



Do they have the latest version of the font tools? Other than that you should ask Apple.

It is OK that the font does not have kerx and kern tables. OpenType fonts should employ a GPOS table instead.
