Hello everybody, I am a new Pte user and of course I can't understand instantly everything about keeping or not the original mode, but one thing is sure : This mode is usefull, this mode has been used successfully quite a lot of times in the past, and it is quite always dangerous to change fundamentals inside any software, just because of compatibilty problems in the future. Moreover JPD gives you as far as I know well documented explanations and proposals... So, I agree with you, he is not the developer in charge to program Pte, but, he is undoubtedly one of the most concerned and qualified people in using Pte, and more than this, a great defender of this software. So please do your best to study his proposal in order to find the best solution for everybody and Pte itself. Thank you in advance. Besides, masks possibilites are great in V5.6, congratulations. Best Rgds. Lionel
