Oh, I see. I did not realize this was an already-discussed issue.
Thanks for you time. Mitch

hola,

i know this but this is not specific to grid, all graphical objects will provoke the same crashes, there's something about freeing graphic objects in 'graph-on-parent' mode.

no time to look further in it.

ciao, sevy

Dear all, I am having a problem with the [grid] GUI object (found in
"unauthorized").

The problem occurs when I use the grid object in an abstraction
(graphing on parent). I make a new patcher window, I create an
object (which is my abstraction containing several grid objects),
now on trying to close the patcher window, Pd crashes. Below is
the the crash log.

I'm using Pd-Extended 0.40.3 Mac OS 10.5.5, MacBook Pro.

Thanks for any help, Mitch
