Mavericks Mail app and Gmail Drafts folder
After installing Mavericks I'm unable to unselect "Store draft messages on the server" and "Store sent messages on the server" checkboxes under my Gmail accounts settings. Unselecting both checkboxes and saving settings works for up to a minute or so - after that the check marks re-appear again by themselves. As a result I end up with dozens of half-finished drafts in the Trash folder after I finish the original and send it out.
I used to have both checkboxes unselected prior to Mavericks, and everything was working fine.
Any suggestions on how to fix this?
