Re: libseed-list question on window.get_size and out arguments

["Alan Knowles" <alan akbkhome com>]

I'd upgrade to 10.10 - I did it the other day without any issue (probably the smoothest upgrade i've done in years...)

That has 2.31 included. I doubt you would get much out of a bug report against an old release (although it was supposed to be LTS..)

Alan
