I have a script to run an experiment that presents stimuli and records answers. The script was running normally in v1.83.04, but since upgrading to 1.84.1 (and same goes for 1.84.2), the script crashes upon start-up, without any messages in the output window.
When down-grading back to 1.83.04, the script runs just fine, so I doubt it is anything to do with the script itself. The PC on which I ran it is also the same (running Win 7).
The script in question - simplified - is uploaded here.
Please let me know if I can help in any way in reproducing this.
