navigating back to card when clicking on TOC does not move back.

Originally reported by Czech Republic distributor ArcData.

When navigating using the table of contents and you try to go back to a previous card by clicking on the previous item in the TOC, does not move the card to the item you wanted to view.

In the TOC, click on the down symbol next to "Electric Junction"
Next, click on the down symbol next to "Subtypes"
Next, click on the down symbol next to "Low Voltage Attachment"
Next, click on "Asset Types" text and the card displays
Next, click on the down symbol next to "Low Voltage Line End"
Next, click on "Asset Types" text and the card displays
Next, click on "Asset Types" text under "Low Voltage Attachment".
At this point you should notice that the card did not move back to the asset types for Low Voltage Attachment.

Start with the interactive viewer at the linked data-dictionary URL and reproduce the table-of-contents sequence involving Electric Junction, Subtypes, Low Voltage Attachment, and Low Voltage Line End. Trace the TOC navigation and card-selection entry points; done means clicking Asset Types under Low Voltage Attachment moves back to that card instead of leaving the previously displayed card visible.
