I noticed the hyperlinks blue buttons for the Conversation Explorer and the Searchable Archive are not working in newest version. Comparing to older sheets, I was able to fix by changing for the Conversation Explorer:
=HYPERLINK("http://hawksey.info/tagsexplorer/?key="&getSheetKey(B9)&"&gid="&getSheetGID("Archive"), "TAGSExplorer")
to
=HYPERLINK("http://hawksey.info/tagsexplorer/?key="&getSheetKey('Readme/Settings'!B6)&"&gid="&getSheetGID(), "TAGSExplorer")
and for the archive, changing:
=HYPERLINK("http://hawksey.info/tagsexplorer/arc.html?key="&getSheetKey(B9)&"&gid="&getSheetGID("Archive"), "TAGS Archive")
to
=HYPERLINK("http://hawksey.info/tagsexplorer/arc.html?key="&getSheetKey('Readme/Settings'!B9)&"&gid="&getSheetGID(), "TAGS Archive")
I am not sure if this is correct, but it works in my newer TAGS now.
