Just though I would let people know: I had an existing database, 5 Reflection switches. 4 switches were firmware 1.4, one was version 1.6. all owrked fine. When upgrading to Toolkit 1.3.2 the Version 1.6 switch decided that the keys would be disabled when the group address that was on Key 1 was turned off. This meant that the switch would not work. Changing the disable key address to Unused fixed the problem, but took a few minutes of head scratching. Gavin
