XI – new release 11.0.43
This new release allows the developer to enable IE6 support in IW XI based applications.
There is a new property AllowIE6 in ServerController. Set it to True to allow your application to run on IE6 without raising the Unknown Browser exception.
Although most things would work on IE6, this property allows you to let IW not block it, but we do not support IE6 in XI and will not provide any support for issues in IE6
