Dutch tax 2000 declaration setup program crashes at exactly the same
point. Cause of this seems to be some memory allocation/corruption
problem. At some point the memory used by the sysMsgQueue, is
allocated again by some HeapAlloc() and happily used by its requester.

I haven't found out why unfortunately.
