Outlook - IMAP Server has closed the connection

I've been using 1.1.3 on Vista with MS Outlook for a while. Recently I've been getting popup messages in OL several times a day saying "IMAP server has closed the connection". I use IMAP to read my Gmail account. I have a cmd file run overnight to open key OL email folders, and get errors if this popup is open.

Is this an issue with PF, or is it a problem with OL communicating with Gmail? I was wondering if the PF and OL threads accessing Gmail at the same time might cause an issue. I've tried increasing the IMAP update interval by 60s and it seems to have improved things

Anyone else seen this or have any thoughts on getting around it?
