Hi Ruslan,

I'll give this a try this week and see if this helps me at all in sorting
out the problem. Though I still don't understand why this only occurs on
Windows and not on Macintosh - maybe because of the speed of updating?

I am certainly looking at your server and client application where I will be
running school clusters (which I will be doing in the near future). But my
own server works best for me for single schools as it allows people to work
on their laptops away from a network and then bring their machine back to
the network to update their changes to and from the server. As I understand
it, you're server (as with most) does not allow this.

Thanks for your help and I'll give your suggestion a try.
