rekordbox video visuals

Hi all

When I add a track with no video (mp3) it ask me to select from a list of video (visuals) that I have. But I have a lot of little video clips and when it pops up with the box it doesn't show them all, it doesn't seem to have a scroll feature for me to scroll through the list. sometimes the list is zoom in I only get to see half the list.

any ideas?

Cheers
