m5list on Core2

[WoeTan]

Hi there.

I am trying to use the m5list on the Core2.
I am using the following Micropython code

(Sorry, I did not get to post as a 'real' code snippet)

from m5stack_ui import M5List
lGraph = M5List(0,0)
h1 = lGraph.add_label('PT1')
h2 = lGraph.add_label('PT2')
lGraph.get_sel_label_index()

Depending on what is selected, I could retrieve the selection with

lGraph.get_sel_label_index()

So, I get 0 or 1.
So far so good.
When nothing is selected, that means the display was touched somewhere not within the list or when the list was created and it was not clicked on a list item, then the function does not return any thing and blocks the Core2 until a manual reset occurs.
Could you please help me to avoid this behaviour?
Thank you
