I have checked the cause, and apparently the problem disappear by removing the use of “Cursor read showWhile:”. The following method: -=-=-=-=-=-=-=-=-= ImageReadWriter>>formFromStream: aBinaryStream "Answer a ColorForm stored on the given stream. closes the stream" | reader readerClass form | readerClass := self readerClassFromStream: aBinaryStream. reader := readerClass new on: aBinaryStream. Cursor read showWhile: [ form := reader nextImage. reader close ]. ^ form -=-=-=-=-=-=-=-=-= May be rewritten as: -=-=-=-=-=-=-=-=-= ImageReadWriter>>formFromStream: aBinaryStream "Answer a ColorForm stored on the given stream. closes the stream" | reader readerClass form | readerClass := self readerClassFromStream: aBinaryStream. reader := readerClass new on: aBinaryStream. form := reader nextImage. reader close. ^ form -=-=-=-=-=-=-=-=-= However, changing the cursor has been around for quite a long time. It is strange that the slow menu is surfacing only now. Any idea why?
