200012609 on WinNT 4 SP5. To reproduce: open URL and drag the blue pane, try dragging very fast over the text, moving, etc. Expected: Just to move the blue pane based on mouse position. Actual: See that the background text as well the text over the blue area becomes selected. Comments: I testing using slow machines it's very easy to observe.
Passing along to mjudge, since he's selection owner.
changing QA contact to eli and setting milestone to m15
Using the provided example this is the expected behavor, the scriptor should have used event.preventDefault() to prevent the selection of the text. I modified the example to use a call to event.preventDefault() and it no longer selects the text (http://3wdesigns.simplenet.com/mozillatests/dragdrop.htm). This bug should be marked as INVALID.
so i am marking it invalid now. I concur this does fix the problem.
Rubber-stamping as Verified/Invalid, since I'm not familiar with the subject area, and trust mjudge. Marco, please do re-open if you believe this resolution is in error. (and keep up the awesome demos! ;)
Eli, roger, do you believe this should be the expected behavior? I believe with Netscape 4.x this behavior was not happening. Looking for input.
