However, users that do not use this module have also reported this problem. In this regard, note that OT/PPP Strip includes a separate extension called Breathing Room - specifically designed to address this problem. If you are getting these errors, I would recommend trying out this extension whether you use OT/PPP Strip or not.
Update: Ken Kampman found that DoubleScroll 2.1.0 caused 1010 errors on his Mac. Updating to version 2.1.2 eliminated them.
