hello, 

i wrote an inquisit 5 script on a mac to be run in an fMRI experiment that runs the task on a windows device. the fmri scanner waits for a "=" key press to start, but when testing this (on a windows device while scanning) the "=" appears in a subsequent answer box on the next trial (while it does not do this on a mac). is there any way to prevent this from happening?

thank you!

Below is a short snippet of the code that should run, you have to press "=" for it start.
