I was having problems with an embedded gliffy diagram on a new page I created. It just would not show up inline. I saw that it had attached the gliffy and png files as attachments to the page.
I deleted the attachments - thinking that they would be a copy of the diagram held in the gliffy system - but now cannot find them within gliffy nor in "Space Admin" trash.
Have they been permanently deleted or is there a copy still hiding somewhere?
