How to disable the explorer function?

in the explorer window:
when i type a letter, number or anything else, i do NOT want the listary window appear. How to disable that function?


it seems that the cpu and memory usage of listary 6 is much more/larger than listary 5. is there any way to optimize this?

and the version 6.2 and 6.3 both crashed two times in only a morning (within several hours. nothing special was done with the software, just normal work. one crash was when right clicking the icon in the task bar)… :joy: :joy: :joy:
