FYI
Just spoke to eCW Support.
Currently, the only way to access eCW HelpHub is using V11 EXE/Desktop mode
V11 EXE - Good
V11 Web (Google Chrome) - Fail
V11 Web Plug-in - Fail
V12 EXE - Does not exist (yet?)
V12 Web (Google Chrome) - Fail
V12 Web Plug-in - Fail
eCW Support says a future, to be released version of V12 will fix the problem.
