Negative time values in Log file & out-of-range responses recorded

I apologize for the hassle but could you post the actual files as attachments?

No hassle at all - DirectRT input and Log output files for one of the problem cases are attached (error occurs on lines 252-253 of the log file). Thanks for taking the time to look at them...

Is it just a coincidence that it happened on the final trial in the sample you attached or is that the norm? i.e., if you sort by the order column. Also, if you use the keyboard rather than the button box, does that affect the 8 vs 9 output in the data file?
