Node Linked to Itself

I am trying to make flow charts for a state machine, and I need to draw a link from a node to itself, but I can only figure out how to draw links between two different nodes. Any help would be greatly appreciated.

Thanks!

We decided a long time ago, not to allow this, There's some visual tricks if you don't have the end of the arrow touch the node just almost loop back but you can't actually have a link to yourself.

Thanks! Using the trick you described, I was able to make the loop!

Any chance this functionality might ever be added? This is the most convenient program that I have ever found for creating diagrams and graphs, but I often needs loops.
