In Library Mode / Loope View, curser is a magnifing glass and you can place it anywhere in the frame and clicking it will zoom in to the designated zoom amount at that location. LRC remembers that zoom location until you pick another. How do you reset the zoom location to the original default center location?
In Preferences, Interface tab, Tweaks section towards the bottom:
there is a checkbox "Zoom clicked point to center". Try changing that.
You may need to restart LrC to see the different behaviour, but it is just a tweak - not night and day!
Incidentally, thorough job [sarc] by Adobe "localizing" their software for the UK market. Or I should say, "its" software, "Center", "Color"... Every single time I explain something here, I make a point of remembering to use the US spelling - and then my spellcheck corrects it back to UK spelling and I have to override - just to match what's seen e.g. in screenshots. Total Quixotic fool's errand on my part!
