Hi Roland,
Thanks, I've downloaded the example and tested it in PB 10.5 - PB 12.5.2 where it works as described and then PB 15 beta where it does not as you noted. When stepping through the debugger, the long value it's passing in to GradientFill are the same. I even tried changing to longptr as the notes say it does no harm in 32 bit and it still doesn't work as it does in the previous versions. I've opened CR 754524 and sending it to engineering.
Thanks,
Pat
