Select from the in to the out point

Hi,

On my time line i chose an in point, and then an out point to select a part of the film.

I want to copy that little part of the film on another time line (another sequence).

During a while, that worked fine doing then "copy", "paste", but now it's blocked, and i don't understand why (did i change the way i was doing it? i don't think so...)

It seems like it doesn't select anything at all when i do "copy".

If i try to do "select in to out" (OPTION A), a message says it can't be done because that would "divide some transitions".

Do you know what i should do to be able to copy and paste that selection?
