changing border color of a slide image after clicking on it

Hallo David

Thank you for your help.

The Procedure looks  like this:

...
...

ExternalCausesProc
      ExternalCausesList
           ExternalCausesTrialProc
               Instruction (TextBox)
               restart2 (Label)
               ExternalCausesSlide (Slide)
               InLine2 (InLineCode)
...
...

After a short Instruction, there is an Image presented on the 
ExternalCausesSlide as a Stimulus (e.g. child is getting a birthday 
present). 
There is also a SoundOut on the ExternalCausesSlide which describes the 
scene in the Image.
Additionaly there are 4 smaller Images as possible answers for the Stimulus 
Image.
I've made an attribute for every Image and the SoundOut in my 
ExternalCausesList.

Subjects should have time to click on one of the 4 target Images until the 
SoundOut was played completely.
I want to highlight the Image a subject chooses by changing the border 
color of that Image to "cyan" (black is my default border color) so the 
subject knows that its answer was registered and it can change the current 
answer (this is another thing i could need some help with).

I tried to implement the following code (which i've found somewhere in this 
google group) for changing the border color to "cyan" and back to "black" 
(default setting) before a new Stimulus is presented:

Dim hitObject As SlideImage
   Set hitObject = 
CSlideImage(ExternalCausesSlide.States("Default").Objects(strHit))       

            hitObject.BorderColor = CColor("cyan")
            hitObject.Draw 
            Sleep 5000

      hitObject.BorderColor = CColor("black")

The current slide should be terminated after the Sound is played so I've 
set  "End Sound Action" to "Terminate"    and "End Action" (in the 
ExternalCausesSlide Properties) to "none".
Now the color changed to "cyan" after the Sound was played  and not 
immediately after the click.

So i've changed the Settings to "End Action" -> "Terminate" and 
"EndSoundAction" -> "Terminate".
Now the color changed immediately after the click occured and remained 
"Cyan" for 5sec before changing back to "black".  
But if the click occured at the end of the SoundOut with less than 5sec 
remaining, there was an interference with the Sound of the following 
Stimulus. 

Then I've tried "End Action" -> "Terminate" and "End Sound Action" -> 
"none".
Now the Color changes immediately after the click and remains for the 5 sec 
no matter if the Sound is completely played or not.
But if no click occurs, there is no termination. 

Now I thought I could use the "Terminate/Terminate"-setting  and a Sleep 
time which is equal to the remaining duration of the sound file after the 
click occured, (something like  Sleep "Duration Sound - RT (Time until 
click?)).
This way, the slide would terminate after the click + Sleep time or if the 
sound file was played completely (if there was no click). 
There would also not be any interference with the following Sound file, 
because the Sleep time is never longer than the Sound file itself.

Actually, it changes back to "black". 
But maybe that is just because "black" ist my default border color and the 
settings are just reset to the default settings after Sleep.

Actually this was the prefered strategy for my project and it worked fine 
except for strHitTest for collecting Mouse Responses and logging the 
correct answer.
Basically my program is completed, but i would like to add some little 
improvements, like this highlighting thing, to make it look better  

I hope my remarks are not too confusing.

Best regards 
Hans
