Many experienced that when we check the embed font option of the htmlbox, the bold and italiac words wont show up. If we uncheck the embed font option, we can not make it masked or do comlex animation.
The trick is:
At design time, type ABC and set A as bold, set B as italiac and C as regular.. You dont need underline font.
Then you can make it masked or do complex animation.
Easy, right ?
