Yes .. I mean the large Preview windows, either Clip Preview or Sequence Preview.
Anyway, I have verified what you have advised me and the result is that I have it well selected, in time line mode.
For more information, the version of the video pad software is v.8.21. I bought this software recently.
But I don't think it's a newer version issue or not. Since the super simple sotfware of windows(movie maker), you do not have
any problem of that nature.
