I had the same problem eons ago and it has disappeared for me.
After adjusting the hooks for the best snug fit..
I use two bungee cords between the two hook handles. Try various strengths of bungee but not extreme short ones.
In fact I slip one of the bungee cords thru a VIVA Paper towel roll for easy access to VIVA Paper Towels.
