--- Comment #9 from Jice <wine at cardot.net> ---
Here is a patch to wine winhlp32 so that it behaves like MS one:

@@ -507,6 +514,16 @@ static BOOL HLPFILE_FindSubFile(HLPFILE* hlpfile, LPCSTR
name, BYTE **subbuf, BY
     WINE_TRACE("looking for file '%s'\n", name);
     ptr = HLPFILE_BPTreeSearch(hlpfile->file_buffer +
GET_UINT(hlpfile->file_buffer, 4),
                                name, comp_FindSubFile);
+    if (!ptr)
+    {   // BUG 23768
+        CHAR c = *name++;
+        if (c == 124)
+        {
+            WINE_TRACE("not found. try '%s'\n", name);
+            ptr = HLPFILE_BPTreeSearch(hlpfile->file_buffer +

+                                       name, comp_FindSubFile);
+        }
+    }
     if (!ptr) return FALSE;
     *subbuf = hlpfile->file_buffer + GET_UINT(ptr, strlen(name)+1);
     if (*subbuf >= hlpfile->file_buffer + hlpfile->file_buffer_size)

please comment on the patch.
