I've installed CCP4 7.0 on a CentOS 6.6 virtual machine.  Trying to run xia2, I'm foiled at the step of Loading Images.  There are no files in the Open dialog, only directories, no matter whether All Files (*.*) or (*) is selected in the Files of type box.  (These are the only two choices.)  Other programs, e.g. Shelx are ok.

Can anyone advise a fix?

Thanks and all best.
