Gerhard, I have to agree with you on many points. Specifically every time you reply with "I don't understand this." I think I speak and understand English pretty well, it's the only language I know. But even I can't understand him in half of his comments, and he used very confusing English in those that I did understand .
I think, as you have already guessed, that he's just expressing his unfamiliarity with your software. It can take weeks to discover and use all the tools properly, the same amount of time as any decent software as feature-rich as yours is. I wonder how long it took him to learn how to use layers in PSP? Weeks or months? Surely it wasn't in one day, as he's expecting to learn ALL the tools in PL32. As well as his being locked into only one way of thinking now. Some of us are not so rigid/inflexible in our abilities to think, reason, and be creative. When some people are taught to stay inside of the lines with one color of paint with one brush and apply it in only one way, there they stay the rest of their lives, and are quite content to do so.
He does raise a few okay points, but those are minor ones, which you agreed might need be worth correcting. Which reminds me to ask something that I've been curious about. Are you the only one programming this software? Or is there a whole team of people writing and testing it? (forgive me for not reading credits and things to find out on my own, like you and others, I too get too busy with other things)
In any case, his posts made for an interesting read, and study, in how some can easily adapt to new things and others cannot. Those that cannot adapt, die.
(PSP falls into that category now.)
