Could you copy here the code for the event handlers involved in all this?

The Diagram handles MouseDown like this:

1. increment ClickCounter
2. if ClickCounter == 2 -> Raise NodeDoubleClicked
3. SetMouseCapture to track subsequent MouseMoves

SetMouseCapture throws an exception when it is called on the diagram you have just made invisible from the DoubleClicked handler; perhaps invisible elements are not allowed to have the mouse capture. You might try hiding the diagram from a timer event, so that the MouseUp handler can exit before you hide the diagram. We'll also check if reordering our MouseDown code a bit would allow such scenario.

Now CaptureMouse is called before raising the event:

Seems to work this way.

1.0.2.23845 is the latest. Sorry, our developers build such pre-release versions on their own systems so the build numbers are not in order. They are correct only for official releases, which we build on a dedicated system.
