         Please notice that this function works by modifying the per-user part
         of MSW registry, which has several implications: first, it is
         sufficient to call it only once (per user) as the changes done by it
         are persistent and, second, if you do not want them to be persistent,
-        you need to call it with @false argument explicitly.
+        you need to call it with @c wxWEBVIEWIE_EMU_DEFAULT argument explicitly.
 
         In particular, this function should be called to allow RunScript() to

         supported at the default emulation level.
 
+        If set to a level higher than installed version, the highest available
+        level will be used instead. @c wxWEBVIEWIE_EMU_IE11 is recommended for
