How to get the Delete key to work for stored imported items

[URExplorer]

Hi,

I just imported a tree from a Treepad document.

Since it contains only Text from the Treepad doc, I'm trying to just manually copy & paste from each Treepad article into the corresponding URD node. That should include the images.

The problem is, that the Delete key doesn't work after importing. The tab for each node says it's a Stored Item. If I toggle off the Stored status, I'm still not able to delete any content from the node.
