To clarify the expected behavior:

Sticky Snapping Off: Window snaps after you release the mouse button (original DF snapping behavior)
Sticky Snapping On: Window (visually) snaps when in specificed pixel range of another window or screen border without releasing mouse button

Basically, snapping works, but Sticky Snapping does not (if the above is the way it's supposed to work). Any ideas?

Thanks

That did it! I had that option disabled. Enabled and now sticky snapping works beautifully - thank you!

Edit: Is this supposed to also work on MDI windows?

Ok - doing some testing. In an MMC window, the MDI child windows snap to the main window but not to each other. Bug or expected behavior? Thanks!
