Hi there, I am a visual neuroscientist and I would like to try out Vision Egg to produce visual stimuli. I have followed the instructions to install all the different components of the software and apparently it has been successfully installed. When I run multi_stim, however, only a black screen appears for a few seconds and I don't see anything. I am running it in a PC (2.4 Ghz) using Windows XP, a Diamond View Monitor (1280x1024 pixels) and Intel(R) 82845G Graphics Controller. Do you have any suggestions about how to overcome this problem? When I run the check config file, I obtain the following results: check-config.py for Vision Egg 0.9.5a2. [2003/09/19 03:54:27 CVS revision 1.19] Beginning configuration check.
