Thanks for getting back to me. Every time I open SPSS or open a data set it just freezes and I have to force quit SPSS. I have never had this problem before I upgraded to 10.7.2, so I'm unsure what to do.
Try restoring permissions in the disk utility app. If that doesn't work, try reinstalling SPSS if you can. Make sure to delete all the files associated with SPSS before you reinstall it. Not your data sets of course!
