keys don't terminate display

mariosav

Hi guys,
Here's the problem I've run into. I have an experiment that works fine on Windows 10 and Windows 7. But, I have a bunch of older Core Duo machines in my lab running Windows XP and on 3 out of 6, the key responses for the same exact experiment and the same latest OpenSesame distribution, don't work. That is, when the a sketchpad (with a picture) is presented and I press the response key the display does not terminate (haven't checked whether the response gets registered at all, but I should). Also, when I press Escape it stops the experiment but Q doesn't quit it afterwards. Any ideas what's going on?
Thanks,
marios

Hi Marios,

Is the capslock on while uppercase keys are not allowed?

Cheers,

no, no...that was the first thing I checked! At first I thought it was the fact that some of the keyboards were USB and others PS/2 but as an experimentalist I ruled out that hypothesis too. I'll go back to check the Windows XP version across computers which are of the same make. Other than that, I'm running out of ideas!

And the keyboard layout? Sometimes Windows automatically switches layout from application to application.

yes, it was the language setting. Switching the language with Alt+Shift did the trick although I don't know exactly how the problem arose (and how to prevent it from happening). All my PCs have Greek and English keyboard inputs installed and I make sure English is selected before running OpenSesame. But I can work around it by adding a sketchpad at the beginning of the experiment to test whether the working keyboard layout is on.
