Yes, I've seen something like this also, specifically while trying to  
scroll one page in the Log activity (XO B4 trackpad, joyride 2301,  
Q2E13), perhaps 4 or 5 times now. I'd assumed I might have been trying  
to scroll at the same moment that 10's of pages of log entries may  
have suddenly arrived, but I'm beginning to doubt that.
