Unintentionally and somehow I activated INSERT mode, without taking notice, and so caused a terrible chaos in some of my staffs.
Ctrl-Z … would have killed to much work done.
so I tried to fix it by moving things back to their intended position, e.g.
- selected from first wrong note up to flow end
- pressed several times (9x) alt-left (with a eigth note selected as raster value).
- this took a significantly increasing amout of time, first reaction was nearly instantly, completing the last key command time took about 30 sec…
there must be something wrong.
