Harry,

I understand what you are saying, it should pick up from the last product
it has received.  This isn't new on 5.0.8 ?  The same problem existed on
the older releases?  The reason I asked this is that Glenn sometimes made
changes and told me about them later. If it's a new change I could regress
back to the old code. If not then I'll pass this onto the new LDM
developer.
