Tnx a lot for your answer & solution. Both parts of your answer do work, though I'll have to get used to enter 'apply' before changing (quite opposite compared to 6.10). And thanks to your post I discovered the separate subtitle-cursor, hidden in the left corner, which, when discovered, is not very difficult to use.
So problems solved, though alltogether I do not really understand this 'change of logics' at NCH/ Videopad.
