I just purchased a MacBook to supplement my PowerBook G4 There is one persistent problem with the MacBook. Very often, particularly after completing a task, for example moving from one web site to another, or changing applications, I find the cursor frozen in position. It does come back to life, but only after 5 or 10 seconds. I have never had anything like this happen on my PowerBook I realize that the MacBook has a slower processor, but this seems like strange place for this to show up. Might it have something to do with using the Intel processor with older PowerPC applications? Running Tiger 10.4.8 Jim
