I have a new install of zd 1.0.4 1833 with a total of three gmail and one yahoo email accounts so far. The largest gmail account (1.5g) is almost always in it's sync state. It's set to sync every 15 minutes. On my other older pc with a slightly older zd it is set to sync every minute, and it didn't have this issue of getting 'stuck' in sync. Anyone know what this might be about? I wonder if this version of zd is somehow less efficient at sync?
