But there's the rub: The trick we're discussing in this thread,
getObject("script:..."), only works with GetObject, not CreateObject;
so we're stuck with the GetObject functionality for this.

I don't see a GetObjectEx function. There's a CreateObjectEx, but not a
GetObjectEx, unfortunately.

Try GetObjectX with a variable number of 2. Sometimes the GetObject doesn't

Thanks. Would you have any suggestions on how to debug the problem with
this technique on Win64? I tried running a test .vbs script with GetObject,
and it failed, too. As I recall, however, I ran the test script at a
command prompt, so might the console mode there be the problem?
