Mouse component clockStr. error

I’m using standalone psychopy 3.03 on win10.
Trying to run a reaction time experiment on a different computer (psychopy 1.9) and I get this error:


Any ideas? I can’t upgrade my class set of computers to 3.03 due to time restriction if that is the issue…

Hi @fragmag, would you please let me know about your mouse params. In particular, please would you tell me what setting you have for “Time relative to” in your mouse component.
