1) Open a resource to the left.
2) Open a non-resource to the right.
3) Drag so that the panels are no longer of the exact same size.
4) Go to Layouts and click the '2 Tile' icon, in order to get them back to the same size again.
>> Logos not only does that; it also decides on its own that the two panels should switch place.
It's bad enough that you've now programmed Logos to always open the first two panels in the opposite position to where I want them, so that I always have to drag them into the right position (I'll write more about that later), but you could at least abstain from subjectively rearranging them again later, so that I have to drag them around a second time.
