Display a stop watch on the screen

Hi,
Are you doing a Libet thing? Anyway, what you want can be quite easy or difficult, depending on the amount of coding you're interested in. What I often do, during a break, is something like
For I = 120 to 1 step -1
	myBreakScreen.Text = "Have a break for " & cstr(i) & " seconds!"
	myBreakScreen.Run
Next I

With myBreakscreen being merely an empty textDisplay, let's call it myBreakScreen. You could tweak this by using a slide with a picture of a stopwatch, embedding an attribute into that, say [TimeLeft] and doing the following:
For I = 120 to 1 step -1
	c.SetAttrib "TimeLeft", i
	myBreakScreen.Run
Next I

Voila! Of course, all these interruptions and whatnot need to be taken into account, so you might have a little more difficulty in getting this to work, but I suppose this is enough as a proof of concept?
Cheers,
Mich

Subject: Display a stop watch on the screen

Hello,

I'm designing an experiment (E-prime 1.1) for which I need a stop
watch to appear on the screen during the experiment.
Pictures appear for 2 seconds (interrupted by cross fixations 500 ms),
and I need subjects to monitor the time as pictures unfold.
I have found no information on the website. I wonder if it could be
possible to do such a thing and, if so, can someone help me?

Many thanks in advance,
Julie
