WebHelp generated from RH11 has empty navigation panes when viewed in IE8, 10, 11, and Chrome. Any solution other than going back to RH9? (This thread - https://forums.adobe.com/thread/1830443 - didn't help.) Thanks.

It appears that there's a number of browser-based display peculiarities in RH11's WebHelp output. I hope someone at Adobe notices this thread ASAP because I have to tell the client by end-of-day tomorrow (Friday) whether there's a solution to their problem (and perhaps yours as well) other than reverting the project to RH9, something that would cause a lot of headaches and lead to a very unhappy client.
