When I delete an email, the email near it, likely below it, deletes also for no reason. I’m using imap with Gmail and I turned on the “confirm delete dialog” that seemed to have fixed it, though it makes a lot more work for me, but now I just deleted an email and the one next to it also deleted. Is there a bug at work here?
The version you are using is 2 removed from the current one. I would suggest that you upgrade, before someone else suggests to, and perhaps that will resolve your problem.
When I check for updates within the product it tells me there is no update available.
The check for updates is not working… has not been for awhile… 
Use this link and grab it from there… grab the latest version (I would do a backup first).
