Fixed bug as reported in Ticket 29 on Sourceforge (https://sourceforge.net/p/quickhash/tickets/29/) wherein users could not select the root directory in the "FileS" tab. Now they can, though I expect this will only work when selecting slave drives and removable drives. If the users selects C:\ the operating system will lock certain files, preventing QuickHash access to the files and generating an exception error.
Also improved the "Copy" tab in as much as the source and destiantion text fields are now read only unless UNC mode is selected. If then deselected, they revert to read only.
