Dialog Box Blank during install ...

… also when running diagnostics to resolve ‘Filesystem Filter Driver not loaded’.

user[at]host:~$ uname -a

 Linux <Hostname> 3.16.0-4-686-pae #1 SMP Debian 3.16.7-ckt25-1 (2016-03-06) i686 GNU/Linux

user[at]host:~$ sudo cat /etc/X11/default-display-manager


For the ‘Filesystem Filter Driver not loaded’ issue, I believe the blank dialog boxes (see screenshot below)

during the install and subsequent running of post-setup.sh were asking loading driver.tar which would (likely) prevent the issue.

So I need to resolve the blank dialog issue first.
