Audio clip edition bugs & strange behaviors in Sonar Platinum

Hello All,
 
I am experiencing some very annoying Sonar Platinum behaviors while editing my AUDIO clips on the " take lanes ".
Most of time everything is working fine, then suddenly those annoying behaviors happens.
 
1 - Let's say i have "take lane 1" and "take lane 2". When i record something on "take lane 2" the new audio clip will "erase" the common measures it have with "take lane 1".
2 - Same goes for copying and pasting clips, even if they aren't on the same take lane, new pasted material will erase any common measure with existing ones even on another take lane. Same thing when i drag and drop clips.
3 - If i open a project made on a older Sonar, sometimes there are several clips on the same take line of a track. In this case the clips overwrite and delete each other so it's impossible to reclaim entire clips.
4 - sometimes i want to copy several clips on 3 take lanes and paste them identicaly at some other measure, when i do the clips are all merged on the same take lane although i never selected " paste to one track " and if i do the " paste to one track " is greyed and can't be checked or unchecked.
5 - sometimes i want to copy a clip from take lane 1 to take lane 3, whatever i do it will be copied on take lane 1.
 
I've read the doc but the french translation is very poor and wasn't able to find any clues anyway.
It realy drives me crazy, thanks in advance for your help.

Hi. Perhaps try comping mode?
(It will mute the previous takes while recording, but easily edited afterwards)
All the best.

I can't say I've ever come across these behaviors before, and I always use Sound on Sound and Blend Old and New.   But that's what those two settings together should do - allow you to layer and move around clips on independent lanes. 
 
When you say that recording or copy > pasting on one lane "erases" the existing clip on a different lane, can that existing partially-deleted clip be slip-edited back to its original length?  IOW, is it the equivalent of the comp tool in that clips on other lanes are auto-slip edited?    Maybe try toggling the recording mode between Comp/Overwrite/Sound on Sound just to be sure that what the UI is displaying is actually what's happening?
 
Also... is this specific to one project or does it happen in all of them?
 

That is weird...    While I have seen overlapping clips on the same lane when copy > pasting from other tracks, I've never had a problem clicking on one (the top-most) and just moving it to a different lane.  But this isn't something I do that often...     The clips aren't grouped in any way, are they?
