recording response

[David McFarlane]

Linda,

Hmm.  I wonder what task you want to perform, because offhand this 
design seems very clumsy -- You present an ImageDisplay for 500 ms, 
then follow that with a Wait object, but since a Wait object does not 
replace the previous visual display, this means that the subject will 
continue to see the ImageDisplay during the Wait.  Why would you do 
such a thing?  Then you go and collect a response to the Wait, which 
you do not want.  Why did you add an input mask to the Wait object in 
the first place?  If you just remove any input mask from the Wait 
object, then you will not get two responses, which seems to be what 
you are asking about.

I must be missing something.
