with the latest version i still have the same problem with pecan as with butterfly
If i switch wifi networks (or wifi -> 3G) then all my accounts reconnect except msn. That one then reports as "network error"

With butterfly when i got into this state it was very hard to recover from it (i think a reboot was somehow needed) But with pecan it is just going into the account settings and press save. Then it can reconnect

So it seems that pecan just time for reconnection is just to little, it just stops a bit to early with it.
