LeiaPlayer slow to open directory

LeiaPlayer version V4.3.41785
Seems slow in opening a directory if there is a large number of items in it.
In LeiaPlayer version V4.3.41785 in internal storage, in downloads I have a large number of pictures, if you tap on the directory it will take time to open compared to a directory with a few items in it.
The Lumepad 1 does not have this problem in Leiaplayer
Please help
