I purchased FontCreator version 12. After updating to version 13, I found some bugs: when I clicked on OpenType Designer: Edit Kerning and OpenType Layout Features button, the message box appeared with the text “The parameter is incorrect”. Then, I clicked OK the message box disappeared and lead me to OpenType Designer. Here I can create features and classes (It also show: The parameter is incorrect when I clicked any buttons as attached pictures). After creating class all buttons (Apply, Ok, Cancel and Help) and other buttons are dead. Pictures are attached.
Please be informed that I work on Khmer Unicode font. Khmer is a single official language of Cambodia. It is spoken by nearly 90% of the country’s population.
Thank in advance for solving this bug.
