Well, as I discovered a solution myself I thought I'd mention it. In fact, going into Options - Preferences - Project - Defaults and checking "Free item positioning" solved this problem. And a whole lot more to be honest. Make sure to restart Reaper after checking it, that's what I had to do in order for it to work. As long as "Free item positioning" remains unchecked there is a lot of confusion and strangeness associated with takes and lanes. For me it was downright counter-intuitive, so I find it a bit surprising that "Free item positioning" isn't enabled by default... This has solved many headaches for me I think... T
