Millisecond Forums

hello, 

i am using an inquisit script for a scanning experiment. while some delays are accounted for (when tested on a separate computer), there is an added delay (about 100 ms) that occurs for the trial below when it is being run in the scanner and only when there is a response. this delay does not occur when testing outside of the scanner (with or without response). is there any way to prevent this or account for it? thank you!
