Dear Mike,

Thanks for the reply.  I don't have gdb etc. set up on my Windows client
at the moment, although I will set up MinGW, if it is needed to get to
the bottom of this.

I do however have a Windows Error Log which contains a stack backtrace,
and I have attached it below.  Please let me know if this is sufficient
information.

Best wishes,

Allan
