That will cause the TTS engine in fullscreen form to initilize. Takes very long time on longet text.
I'm planning to add the TTS engine in only main form.
When user presses fullscreen, the TTS will be paused. (quick)
Then copy rtf from main form to the fullscreen form. (will take time)
Hide the main form, show the fullscreen form.
Resume TTS and highlight RTB in fullscreen form.
oh well, i didn't think it'd be a particularly practical idea when i came up with it anyway.
