Lingering arrows after delete

[Scott]

Every once and a while when I delete an arrow it sticks around, at least in the display.  When this happens I've usually saved, closed, and re-opened and the phantom arrow was gone.  I always thought it to be a random error... 

But today, I think I figured out that this isn't a random error, but occurs in a very specific case.  I believe I noticed when this happens and I was able to recreate the error as follows.

1) Start out with a graph node.  

2) Make two new graph nodes and make them children of the first graph node.  

3) Rename one of the two child nodes.

4) Delete the arrow to the child node that was not renamed.  It will disappear.

5) Delete the arrow to the child node that was renamed.  It will not disappear.

I haven't looked at the source code, but I'm guessing there is some list of node names associated with this arrow that is out of sync because of the rename.

Hopefully this report is useful.

Best,

Scott

Yep, does it for me too. I'll try to figure out what's going on. Thanks.
