Thunderbird is installed on both machines but the inbox and other message folders I use are just on the one machine (in Account Settings:Server Settings: Message Storage / local directory-- file location has address on remote machine), so I have just one set of folders regardless whether I'm in on the desktop or wandering with the laptop. When Thunderbird on the laptop goes to compact folders, the wireless router stops broadcasting, possibly due to some kind of overload, and the operation never finishes. If the folders don't have a lot of deleted messages in them, sometimes the router will survive and the operation will complete. I still can compact on the desktop without trouble. Is there anything I can do so the router doesn't crash when I try to compact from the laptop? TIA
