Hi,
In the 2nd inlet, you should prepend an index to your list (index, value1, value2). If you send a list without an index before, the first value of your list will be understood like the index. I don't clip the number of lists so when the index is high, Max crashes (I'm going to fix it),then if your 1st value is high then Max crashes.
I've try on mac and windows, with two integer in the left inlet (value1, value2) and two integer the right inlet with prepend 1 (1, value1, value2), it works.
Thanks for feedback,
Pierre
