I don't know how familiar you are with irc channels , but that is pretty much standard behaviour. So no its definitely not a reason to close channel. I rather help people who keep trying to learn pharo than people who give up too easily to be frank with you.

I try a direct use of this method, and the same problem occurs under Wine/Windows. Is ti a problem with native boost? Is it different Cairo lib used for Linux and Windows/Mac VM?

SystemWindow instances can't be garbage-collected

by Max Leske

First off: <rant>why do we have an IRC channel if nobody seems to be listening??</rant> Sorry about that. Hereâs my original question as posted on IRC: Hi guys. I have a couple of SystemWindow instances sitting around in my image which canât be garbage collected. They all once showed a debugger but that debugger seems to be only referenced by the window. Iâm kind of running in circles. Does anyone have an idea how to find the root pointers which prevent garbage collection of an object?
