Weird latency data

https://forums.millisecond.com/Topic29228.aspx

Hi,

I'm running a study. The script is in Inquisit 5. When I run on my laptop using Inquisit 5, the latency data look normal, but when I run participants using Inquisit Player 6, the latency data look weird. 

For example, latency for one surveypage or trial is 4294425619.

I don't have any code in my script to record data in certain ways. 

Any idea why this happens?

Thank you!

When I run myself using Inquisit 6, it's also showing weird latency data but with a negative sign such as -5773497074.

Thank you. I am able to reproduce this and this definitely looks like a bug pertaining to the <likert> element's logging of latency data. We'll get that fixed ASAP.

The issue should be resolved in version 6.2.1 available at https://www.millisecond.com/download (Inquisit Lab) and selectable in the version menu for your web experiments.
