I tried to reset the profile and copied all information to a new sheet making sure no formulas was copied but no improvments. Seems to be when I leave a cell it takes time.
I disabled spelling-check as well, no improvement.
Hesitates a bit for fiddling with Sun-version (well, it is Oracle version now days I beleve
). The most important is my computer at work and there is no rooms for downtime right now.
Will continue looking for a source to the delay.
