A strange one. I installed Zibra desktop on one PC - works fine offline, syncs up when online, etc.

Installed on another PC, I get

"This document cannot be displayed while offline. To go online, uncheck Work Offline from the File menu"

when starting the desktop offline. Just can't see what I've done differently. I can start up via Firefox, though, by pointing at localhost:7633, so the background process is running ...

Any ideas?
