Dont take the address of the `wstring`, use `wndName.ptr` instead.

wstring is internally a fat pointer that looks like this:

struct wstring {
     size_t length;
     immutable(wchar)* ptr;
}

When taking the address `&wndName`, you get a pointer to this 
struct on the stack, not the actual string literal.
