Searched the forums and found one "access violation" post, but it does not seem to be the same issue.
I use PocomailPE on the email voyager usb stick. Whenever I try to reply to an email, I get the error access violation at address 0040531F.
I tried renaming and creating a new poco.ini file and the only thing that changed was the second part of the error message. It went from (Read of address 02120004) to (01c7c000.)
Creating a new message works just fine, but there is no way to reply to any using the reply buttons.
Thank you for your help.
