Best I can tell, the behavioral model from the user side is to move the cursor far enough beyond the edge and the panel will appear. Based on that behavioral model, I think the expectation would be that if the cursor is moving relatively quickly when it get's to the edge it'll get to the magic distance beyond the edge more quickly than if the cursor is moving relatively slowly. Another potential behavioral model could be a force model, where the panel unhides when the edge is hit with a certain degree of "force". Force based models can be quite complex though since it usually requires some kind of elastic resistance at the edge to allow triggering when moving the cursor relatively slowly. Also, since there are very few uses of the cursor within the screen boundaries that employ a force model, the user needs to maintain quite different behavioral models of the the cursor behavior at the edge versus the middle of the screen. It doesn't mean it can't be done, but I think it can be quite tricky to do well. A simple magic distance past the edge behavior is usually much simpler and more predictable I think and should handle the fast versus slow edge approaches just fine. Hope this helps, Andrew
