I tried to add a new address to the Wallet Balance page, and the dollar amount disappeared. This is on the latest Development preview. When I replaced the ConfigData.xml with the latest backup, the dollar amount came back. I was able to edit the ConfigData.xml file and swap an empty address for the new one I wanted to add, in the 2 places I found it, and it works fine.
Thanks for your report
1) Did the USD amount disappear for all addresses or was it only for the new address you added where it didn't show up?
2) Did any of the entries indicate "Update failed" in red text?
The USD amount disappeared for all addresses. The top header says Balance ($0.00), but the column under it, is totally blank. The amount of Bitcoin is there for all addresses.
I have 3 sources of internet so I can swap between them when I do get "Update failed", that is not part of the problem.
Thank you for looking into this.
