This question was received by a customer in the Notes from Lotus Support blog....
Language specific cumulative DWA hotfixes for more than one language must be requested from support for every special language combination.
Forms7.nsf is the very problem, because it contains language specific design elements, but when applying the cumulative DWA hotfix, one must replace forms7.nsf which results in the loss of language specific design elements if an cumulative DWA hotfix with less languages built in is applied than languages are installed on the Domino server.
Why not providing the cumulative DWA hotfix in the same way as Language Packs where one can add additional languages to a Domino server? This may speed up response time to customer requests and may lower support costs for IBM.
