Some Subject Lines and Sender Lines Are Blank, No Preview

[jsaffer]

Some of the e-mail subject line and sender lines are blank and I can't see anything in preview. I know these are real e-mail messages because I see them on the e-mail server. Any idea how to correct this so I can see the subject line and sender line for all the e-mails that are listed, not just some. I've attached a screenshot.

Install this beta version first, it will install fine over the top and has a fix relevant to this problem.

Also under Settings >> General >> Checking Mail >> set the Spam Throttle to 350-500 lines, restart MailWasher after making the change.
