Has anyone else noticed this? I inserted 24 Fan-in/Fan-out source arrows. I go the next page to insert the Fan-in/Fan-out destination arrows. When I click to insert the first destination, instead of getting an intermediate dialog to enter a code, the symbol immediately inserts with no opportunity to enter a code. The wire segment on the left of the destination doesn't get assigned to the _MULTI_WIRE layer either. The second time I insert a destination arrow on the page everything works as expected.
I recall encountering an error similar to this a few months ago.
It had to do with the fan-in/fan-out source destination markers with the same problem. Insert source, and then insert a blank destination on a seperate sheet.
I deleted the destination marker as a component and inserted the marker again then the dialog appeared.
