TextDisplay: flush input buffer

[Justin Lolofie]

I am using a msgbox after a TextDisplay to ask if the experiment should
continue on:

  goOn = MsgBox("Continue?",4,"Press Y or N") ' 6 for yet, 7 for no

The problem that I am experiencing is that in the previous TextDisplay,
when a user presses {SPACE}, it is also affecting the msgbox that follows
the TextDisplay. (and SPACE is like a button click when a msgbox has
focus)

Under "Advanced" in the TextDisplay properties window, there is a "flush
input buffer" but this is already set to "yes" and also this seems to
flush the input when the TextDisplay initializes.

So I guess what I'm trying to figure out is either:

1. How do you flush the input buffer AFTER a TextDisplay?

or

2. How can I check what key was entered into a TextDisplay? (to eliminate
the msgbox altogether)



Thank you for any advice,
