In the latest download (6.2.0.1), I made some changes to always honor the tree scroll options, so if you uncheck
Tools | Options | Tree | Scroll horizontally on selected change to keep text visible
and
Tools | Options | Tree | Scroll item to top when going to item
there should be no more automatic scrolling in the tree.
Still trying to digest the last two items. A screen recording and other info from
https://www.kinook.com/Forum/showthread.php?t=3038
could be helpful.
Thanks.
