Maybe I just wasn't able to follow the conversation properly, but if you open a Transcript in 10243 (dev) and, say, search for the class "Morph," you will get:

ERROR: Morph class>>overridesSelectors
ERROR: Morph class>>superSenderSelectors
ERROR: Morph class>>conflictsSelectors
ERROR: Morph class>>overridesSelectors
ERROR: Morph class>>superSenderSelectors
ERROR: Morph class>>conflictsSelectors

In fact, anytime you do anything (save a method, etc...), it seems you get these messages, and yet things seem to be working.
