I have installed the TTF fonts in windows, then copied them to the Resources folder under a subfolder called Fonts.
Now when I look at the font dropdown for a label, all the system fonts are there as before, but above them in a separate section separated by a horizontal divider are my three new fonts. However if I select one, the second dropdown below it (which normally has sub-type such as semi bold, italic etc) has no options and is blank. The label does not update to my font and if I tab off and back on again, it has switched back to the previous system font that was selected. So somehow it is picking up that it should have new fonts installed, but when you try and select them they don't work.
Does anyone know why this might be?
