Well, I don't have problems in phrasing the question, except for the lack of knowledge of the english language.

My problem is, that I spend hours and hours to find the solution myself,
because I think I can't waste somebody's time with my problems.
But I think often asking even simple questions here will get you at least a hint where to look further.

That is what I have to learn.

And perhaps somebody will learn even from your question.
