tx 875 - not linking

Hi

we've got a recurring problem with 2 tx 875 tills. They both recognise each other (the irc reports etc work and I can send buttons from one to the other)

However, they are no longer talking to each other when you enter a clerk number - they are working independently. Tabs are only available on the till they were created on.

We've had this issue before, but can't recall how it was solved.

I think it was down to one till having open tabs on it and losing the connection momentarily (not sure could be talking c**p)

Also, Is there a way we can view a report of all open tabs. I've been through the options and can't seem to find it (sure I saw it before)

thanks
