Input text field won't allow input!!!!!

I know this was posted forever ago, but here's a solution that may help some of you...

I just encountered the same issue and after a few hours of messing with my code, I found a solution (for my problem at least).

My textField was using embedded fonts like:
txtBox.defaultTextFormat = Fonts.defaultFontBoldFormat;
txtBox.embedFonts = true;

Although I was setting the defaultTextFormat, I needed to also SET the current format, so my code ended up like:
txtBox.defaultTextFormat = Fonts.defaultFontBoldFormat;
txtBox.setTextFormat(Fonts.defaultFontBoldFormat);
txtBox.embedFonts = true;

Hope this helps someone
