Delay in Windows 7 for displaying images (Case 2143)

[rkozink]

We are running an experiment where we present subjects with some questions and then show them a series of images. We recently upgraded from v2008 on an XP machine (where the task worked fine) to v2012 on a Windows 7 machine. When presenting the images, there is about a 1 second delay (blank screen) between the presentation of the images. I have reduced their color depth to 8 BPP and converted them to bmp, as recommended. However, the delay is still present. We also experience a delay in the display of the questions when a quick style is used. After removing the quick style, the delay between the questions disappeared.
Thanks
