On eisy:
I've managed to upgrade to IoX v5.7.0 and I had previously upgraded to Polygot v3.2.4. Didn't see some of the issues from above (e.g. all programs being disabled). I connect to the device via 2 machines inside my home network. On both, I've cleared the Java "temporary files" completely, which should include cache and applications.

using the above link, I grabbed a new (latest???) copy of the IoX Launcher app on both my machines. Interestingly, my desktop finds the eisy device and I can see that it's running IoX v5.7.0 but... the laptap IoX Launcher comes up empty with no eisy devices listed. The only difference I can see is one is on WiFi (laptop) and the other is on a hard LAN connection.
Multiple restarts of everything. The eisy is on DHCP and can be pinged from both machines. I"m confused and would love some insight from someone more knowledgeable.
