Same for me, Technical ... never a problem with Mailwasher. I had MailWasher before having avast, so, I am not sure why ctb is having a problem. I have even used Mailwasher with my email client (Earthlink) open.

I do this after reading much email to see if new email is now on the server.
ctb ... have you tried un-installing and re-installing MailWasher?
