The application broadcasting packets through UDP on the network every second or so. This thing is very dependant on network conditions.
I have still not found a fix to the hangs, so I am going to close this question but the supplier (Bond International Software) has released a newer version so we are going to upgrade to that to see if it makes a difference.
If anyone has any problems in the future with Bond or Adapt then please get in touch with me through this website or email me - neilmrobb -@- gmail.com
