Thanks, it works. Now, we have a followup problem in BOLatexStream BOLatexStream>>print: anObject        anObject isNil                ifTrue: [ ^ self ].        anObject isBlock                ifTrue: [ anObject value ]                ifFalse: [ self nextPutAll: anObject displayString ] displayString is deprecated, and I am not quite sure what it should be replaced with. I guess it should be printString, or we should just delegate to the print: of the inner stream. What do you say?
