First backup attempt with HDM 14. When the backup completes (Overall progress 100% and shows Succeeded) I am not able to dismiss the window. The only button is Cancel and it is greyed out. I'll have to kill it via task manager. Windows 7 Ultimate x64.
This is a long time. But I would prefer to wait, even for an hour. Interrupt the Paragon process is dangerous.
I would avoid canceling it when the message that appears in the window is "Rebuilding partition info ..."
