Cursor only shows progress if hovering over "Dicom Field" column

[driusan]

In the DICOM de-identifier tab, after clicking "De-identify" the only way to tell that it's currently working is by hovering the mouse over the "Dicom Field" column of the table and seeing that the cursor changes to a spinning wheel.

If you hover anywhere else, the cursor goes back to normal and it looks like the progress is done but nothing has happened.
