Sometimes when I'm dragging a selection downward in a resource, as soon as the resource starts to scroll down, the anchor from the beginning of the selection suddenly jumps to a new location.
This one is hard to reproduce consistently, but by trying over and over several times I was able to get a screen capture video of it happening. Here's a link to that: http://www.screencast.com/t/TLqSdcsz (the jump happens at about 3 seconds in). And attached is the log file from that session.
Here's a freeze-frame from the video showing where the selection started:
And here's a freeze-frame showing where the anchor has suddenly jumped to a new location, without me releasing the mouse button at all:
It's a rather short chapter, only a screen or two worth. Certainly nowhere as long as the maximum allowable selection.
