Copy-paste actions bug

Note: I am experiencing this issue on Mac, I am not sure if it's also present in the Windows version.
I have a couple of action sequences that I usually copy/paste from one scene to another, like on mouse over events that will change the cursor when it's over some scene objects.
This causes a very erratic behaviour: sometimes when going back on certain scenes, the actions are repeated multiple times. (I can see "Set cursor 'ARROW'" six or seven times in a sequence, for example)
When deleting the extra ones, they disappear from other scenes as well, sometimes deleting even the first one (so that I have to recreate it)
This is very frustrating, because every once in a while I have to go trough all scenes to make sure there are no missing or duplicated actions on every single object.

Could it be that bug?

Yes, seems like this is indeed the issue!
I am not sure how to proceed at this point, doing all these actions manually would take me ages.
Maybe it's a good idea to hold on all the copy/paste actions until a new version of Visionaire is out, hopefully it won't be long
