The "Storage Type" label of the grid's third column title under the "Storage" tab appears in the "New Domain" dialog (to the right of the "Name" and "Data Center" boxes - between them high-wise) immediately when opening the dialog, and disappears after ~2 seconds, or when moving the mouse cursor, or when trying to take a screenshot. It seems that the "New Domain" dialog becomes transparent in this location for short time.

It can be reproduced by taking the laptop out of the doc, this way the screen resolution relocates the dialog where the title label is behind the place I described the label appears, or manully relocate the dialog there.

How reproducible:
On Linux with Firefox 7.0 - always
On Windows - didn't manage to reproduce
