Sorry it's been so quiet lately. We've had lots of people away with a really bad flu, I was away for 3 weeks but we finally managed to get everyone back on board mid-week this week. All going well, we'll have a new mobile version out next week with multiple accounts and more setting screen options, also a version of Mailwasher Pro which will sync all your settings to the mobile version.
One of the developers who wasn't away or sick spent most of the time continuing to make the backend scalable and setting it up on our production servers.
We're aware of the bugs reported by people and this next version should fix blank screens and other anomalies.
