I didn't change the version number but know the name of attach files appears in the EditField just under the subject, before the content of the email. I didn't find yet a way in RealBasic to indicate the size of an email (I think this instruction doesn't exist).
A bug in RealBasic cause trouble with drawer window if the size of the main window was biggest, that's why we can't resize it.
There's no way to import word but you will find 2 TXT file in "~:Library:Preferences:MyPopBarrier:", "Dictionnaire bloquer.txt" which is the list of Block words and "Dictionnaire laisser-passer.txt" which is the list of Let pass words. You can edit them and save them in MacOSRoman (do not edit when MyPopBarrier is running !)
There's another way than double-click to block email, you can use arrow key (explained in About MyPopBarrier).
