ActiveMovie window pops up (case 3712)

[rbvance]

Several experiments used to run perfectly on our laptop. Recently, when we try to run them, the message "ActiveMovie Window" shows in the task bar (next to the DirectRT). Actually, there is a second DirectRT icon without the words, then "ActiveMovie Window." If you click on one of these buttons, the screen goes black and the program crashes. We have to end program ("Execute DirectRT not responding") and log off. It happens randomly across several experiments that are identical in format. It doesn't seem to matter whether or not the button box is plugged in. Thoughts?

I just tried running these experiments on my desktop--no problems. The laptop has an XP operating system.
