Description Dav Glass 2007-11-20 08:58:03 PST

During YUI Release tests we found that in Safari 3.x (and Nightlies):

Moving your mouse anywhere in the document results in a mousemove event being traced. Holding the mouse button down and moving your mouse anywhere in the document also results in a mousemove event being traced ... until you mouse over the scrollbars around a content div with overflow:scroll. mousemove no longer bubbles to the document (unless you move your mouse across the scroll bar really fast)

Test Case attached as URL.

In addition to fixing the reported bug, I think this will have the effect of matching how hover effects work in native Windows scrollbars.  I tested in Notepad, and saw that the hover effect doesn't show when the mouse is pressed and you rollover the scrollbar.

I need help testing this on other platforms though, to make sure this doesn't break the hover effect on those scrollbars.
