New imap problem

In process of trying to work out a problem with a message "lost" in my  
gmail mailbox, (which problem is not Balsa related in any way,)  I  
tried using the imap gmail mailbox I set up a few weeks ago.  I could  
click on some of the mailboxes/folders, but none of them changed the  
actual display of the message list from the previous (pop3 or local)  
mailbox displayed.  Some actions just totally froze balsa.  I deleted  
the mailbox and recreated it - basically the same behavior.  Using  
G_MESSAGES_DEBUG=imap, the only relevant line I've noticed at all is an  
occasional "(balsa:17940): libnetclient-DEBUG: finalised connection to  
imap.gmail.com" with no direct connection to what I click on or what is  
displayed.  I have deleted and readded as an imap folder, but it just  
seems to time out.  I've run wireshark, and it sends an imap(143) [SYN]  
Seq=0 Len=0 MSS=1460 SACK_PERM=1 TSval=648291406 TSecr=0 WS=128"  
followed by TCP Retransmission packets at 1, 2, 4, 8, 16, 32, 64, and  
128 seconds and then another set with the same timing.  I assume a  
simple password failure would get some explicit error message.

I do eventually get a popup about failure scanning the gmail imap  
folder (I have so far failed to capture the exact error) but wireshark  
shows it's going to the right ip address, and pinging that address  
succeeds.

I have two other servers with imap set up (also just for  
troubleshooting, not for routine use) and they seem to be working fine.

Any thoughts or suggestions as to how to try to figure out what the  
problem is?
