It should :( The Excel etc demos all work fine with very similar
constructs. You could try:
which due to an implementation detail will ensure that a VT_BOOL is
returned - however, this should not be necessary.
So no real clue I am afraid :( If I could repro the error, I could
probably determine the problem.

Well, the Ctrl+C key is being hit _before_ Python code is entered. In
this case we possibly do _not_ want Python to handle the exception - for
all we know, the object itself has handled the Ctrl+C key, and is
calling back into Python to handle it.
