I made several changes (added an Alyseum AL-88c, upgraded a PC and moved to CopperLan 1.4.2) so it might be hard to tell why, but now, after switching to another snapshot once or twice, the Restore Snapshot window opens and hangs saying Loading File. The Snapshot options window doesn't appear; all until I close and re-open CopperLan Manager.
Also, should there be any problem using different versions of the CopperLan Manager on different PCs on the same network? (Windows XP, Version 1.3 and Version 1.4)?
