Help needed, Opera scene in 50Hz

I think that I've solved it!

Writing about the problem made me think of it in new ways, thanks everyone!

Instead of F9 (Pause execution until the music passes through predetermined point) I use a basic wait command thats longer than the time the choice windows is up, that way it doesn't matter how fast you chose the next line.

Now I just have to adjust all the wait times in the rest of the scene..
