I've tried to Google it, but the only thing I found, that it makes problems in other packages too. Am I missing something? This was introduced somewhere in 3.9 I think, but I'm not sure where and why. Does someone know? Thanks in advance,

It enables the use of context (yellow button) menus on arbitrary Morphs. 
I'm not sure what you mean by "it breaks the yellowButtonPressed event 
in mouseDown: methods" though. Do you have a more specific description 
of the problems you are encountering?
