hi list,

i have strange behavior using Pd.

When I do some patching in Pd, Ubuntu suddenly logouts, and I loss my current data.

I don't know what causes this problem.

Strange thins is, this unexpected sudden logout occurs only when I'm using Pd. Another application doesn't occur this problem.

I attached the Pd patch.

thanks,
akntk
