Dictionary attack not working black screen

[philsmd]

-a 3 or --attack-mode 3 enables according to --help and the wiki a mask attack ( https://hashcat.net/wiki/doku.php?id=mask_attack ).

-a 0 must be used if you want to run a dictionary attack. So it seems this is no problem of oclHashcat, you just use the wrong command line parameters (i.e. attack mode).
