Hello
I was very happy having found this program for free.
I started to do a mindmap about the whole semester of anatomy that I studied.

Until I tried to move a node…
and the half of the other nodes moved. Until I had to reduce the zoom to 25% to see them.
I tried doubleclicking them, or just move them … nothing

Why does it behave like this?

Wasn't it easier to make them draggable by mouse? singularly or in group?

I can't move them even not one by one.

It's a pity, every time I try a free program,
it means hour of time to set it up, find things read through, subscribe to forums, search help….
disinstall, install a new one.

Is there a way to manage let's say 15 nodes that develop in 10 underlevels, with every level 10 nodes?
And then move and organize them?

Tanks for reading :)
