Thanks for this wonderful program, which is helping me organize stock market data.
I am using KeyNote NF v.1.7.8.1 on Win XP.
Coming to the bug ... I have a virtual node linked to a text file.
I have mirrored this virtual node on a separate note. (Using command --> Lift Subtree --> Graft Subtree here as Mirror)
Any change I make in the virtual node is immediately saved to the original text file. But the changes in the mirror node are not always saved, although updates the virtual node immediately.
In other words, changes in the virtual node are saved without any trouble, whereas changes in the mirror are not always saved.
Thanks for creating this great program, and hope you will look into this issue.
