I updated Nautilus few minutes ago. After drag & drop sometimes it creates a dragged icon that will never be dropped again. Also blue rectangle markers can be dragged. It moves in front of every other UI element (including other apps and even in front of Squeekboard). Sometimes I swipe fingers over screen, it moves, sometimes it does not. Closing Nautilus is the only way to remove it from screen.
I believe so, approximately. Speaking totally off the top of my head:
uninstall it
install the specific version that you want
then use the apt ‘pin’ functionality to keep that version
That won’t get updated at all though. Maybe an apt guru can even do better (whereas, based on what I am suggesting, you would have to keep an eye out for a later update and then remove the pin once a later update is available). Maybe you could write a cron job to check the package version and just notify you when it changes (and you could then eyeball the changelog).
There are of course no guarantees that the later update works where the current version does not. That is, there may be updates that are unrelated to the problem that you are experiencing, and do not fix that problem.
