Thanks for your help here but I have download the zip file to my Downloads folder but when i run the script it never asks me to select a file just comes up with the warning "no files found"'. Should the script ask for the file or try and find it itself? The Xterm seems to suggest a segmentation fault? Not sure why but zenity didn't appear in either my HAM or FAM and it sounds like the poster on the link I highlighted had the same issue.
