Hallo!
i've just encountered a problem about receiving~ from a send~ located in a subpatch which is switch~ed off. after switch~ing off, the [receive~] repeats the last 64 samples it got, over and over again, resulting in an annoying squeal. [throw~] and [catch~] do not behave this way. browsing the archive, i found that david mccallum already reported this behaviour in 2003, with pd 0.36, but unfortunately he did not get any responses.

I just experienced the same bug yesterday ... :)
