Bob, that is what what I observe. Here is what I believe is happening: VS.Not has a 'thunking' layer between its excution layer aka 'the CLR(Common Language Runtime)' aka 'virtual machine' aka 'Managed Code' and UniObjects, which is a dll that is compiled into machine code. For some reason this 'Interop Com Service' as Microsoft calls it, spawns off multiple threads that manipulate the UniDynArray. Those threads cross and mangle the array.
I wonder if there is a way to make sure that one thread completes before the next one is started. A way to protect the UniArray from multiple access.

If there are multiple threads and no locks then mangling could be expected if a later launched thread assaults part of the array before the earlier launched thread writes it back. Just a thought.
