Hi Dave, my friend use inquisit 4.0.0.0, the program runs fluently oh his win7. My colleagues use inquisit 4.0.4.0. It runs jerky. It seems that the latest version doesn't help to solve the problem. Hope to hear from you soon.

I have already updated the inquisit to version 4.0.5.0. It doesn't help. Could you give me more advice?

Next step: Check whether the machine's graphics card driver is up-to-date. If not, update it to the latest version available from the vendor.

I have already updated the graphics card drivers. It doesn't work.

Might be a codec issue then. You can try working with a tool likehttp://www.codecguide.com/download_other.htm#codectweaktoolto try to detect / fix broken codecs and re-register the base DirectShow filters or set the system to use an alternative decoder (if available). I strongly recommend creating system restore points prior to making any changes.En- or disabling hardware acceleration for video rendering via your display adapter's settings may also help.While only partly applicable to the problem at hand, the video playback issues FAQ at http://www.codecguide.com/faq_playback_issues.htm may offer some additional ideas.

I have already tried the codec yesterday. It doesn't help.

> I have already tried the codec yesterday. It doesn't help.                                What exactly did you do? It's entirely unclear what "trying the codec" is supposed to mean.

I have already done this yesterday. Download the codec from internet and install on the computer. It doesn't work.

Which codec? From where? Please be specific. And there should be no reason one would have to download a codec for properly encoded WMVs on Win7 -- Win7 has those natively. It is thus unlikely that whatever you did would have any positive effect, it might even make things worse.

It is from the same place that you offered. Believe me, I have already asked many people to help include the experiment assistant in the lab. He told me maybe I should choose another software to fix this problem, for example, presentation or pyschopy. That is my last option, I am still looking forward your suggestion.
