Freezes when trying to resize ntfs partition
I wanted to shrink a 120 gb ntfs partition. It said it could resize it down by 20 gb so I went ahead and did it. After showing a spinner for a bit next to the device, it f**kd up itself and all windows behind it and decided to get a gray overlay with no intention to ever come alive again.
Please implement proper asynchronicity and error reporting. A GUI never has to freeze for a background process even if that gets stuck.
