ML opens to blank questionnaire, can't force-skip

Hi,

On one of my computers on which I recently installed ML, every questionnaire/experiment I try to run opens the typical purple background, but nothing else is displayed - ie the questionnaire is blank. Trying to force-skip to the end using ctrl-alt-shift-right does nothing. I have to kill ML from the windows task manager.

I'm running ML 2004 and Vista, on a multi-monitor (3) computer system.

These questionnaire files work on other computers.

Thanks,

Jon

If this happens with the basic samples, then it may be a permissions issue. Right click on the c:\MediaLab folder and then choose, Properties and then Security. If you then click on "Users", is every kind of control checked?

Yes, all permissions are given to both the user and SYSTEM. I have this installed in a subdir of the root, has that ever been a problem?

And does this in fact happen for the basic samples that come with MediaLab?

Our lab is also experiencing the open to blank screen problem. We recently installed ML 2006 on a machine running Vista. All permissions are checked. This problem occurs with the sample files as well. Are there any known incompatibility issues with Vista?
