If a user attempts to add a 2nd service reference to a component that already has one reference defined, the editor popup to define that reference can be difficult to get to display.

In moving the cursor horizontally from the component to the purple chevron to create the reference, the user can easily cause the delete/promote/etc. popup to appear.

The only way I could reliably get the editor popup to define the 2nd reference to appear was if I moved the cursor close to the edge of the purple chevron associated with the component. There's a small margin of error here, however, as if the user moves the cursor to far from that edge, he can no longer cause the editor popup to define the 2nd reference to appear.

See the attached quicktime movie for an example.
