In Cubase 10.5 in Edit > Preferences > Transport you can turn off the “cycle” feature in the ruler AND opt to click anywhere in track view to place the cursor (instead of SHIFT+ ALT+ Click).
Really.? I’d seen that first one you mention (turning off ‘Cycle’ in the ruler) but hadn’'t noticed that second one… (its a new Preference setting, yes.?) And, to be clear, you’re not just clicking in ‘empty space’ to locate the cursor…? Would be amazing if so…
(Not at my machine tonight, so will have to check tomorrow)
Ah.! Ok thanks - that ‘clicking in empty space’ preference (no modifier) has been around for a while; clicking on an Event/Part (with modifier) was new when brought in at v9.5 I think.
