I don't have the original message in my inbox any more, so I'm replying to the list. We use SPSS-11 on a mix of G3 and G4 machines with OSX2.5 around here and none seem to be experiencing the slowness you're referring to. We do have a gigabyte of RAM on these machines, so that may make a difference. Can't recommend a fix or workaround. Sorry. Charles Pearce <charlesp at ksu.edu>
