How to fade from slide1 to slide2 (inline?)

[Dr Hackenbush]

Dear All,

I am experiencing the same problems as Erika Nyhus. Is there anyone
who has found a solution yet?  In my current experiment, I want to
include a confidence rating so that I know how confident participants
are in their answers. And I would like to measure this by the length
of time they press the response button, just like in Erika's
experiment. I want to use a moving bar which indicates the length of
the button response. Does anyone know how this can be programmed in e-
prime?

Best regards,

Dirk
