Triggers and Locos

[dzien50]

On one of my larger layouts I have many locos and also use triggers, however I find that the list that comes up when you select trigger does not show all the locos nor the top line " any loco" the list is the height of the screen but I cannot find a way to scroll it up and down to get the loco I want. Any suggestions please
Thanks
PJ
