Full_Name: Jeff Benjamin Version: 1.7.1 OS: XP Home Edition Submission from: (NULL) (131.202.163.72) Recently have been using R1.7.1 on a new laptop computer. System and software worked fine for at least two weeks. Now the entire OS slows down to the point where one would think it had frozen. I feel there must be a compatibility issue between R and XP Home (including auto updates / service packs) as these are the only items I have changed recently. Has anyone else had any similar problems lately? Jeff
