Usb-creator does not select ISO for creating USB key

[Carla Sella]

I have just upgraded to Quantal Final from Precise.
I was trying to create a live USB key for testing, but Usb-creator does not select the ISO file I want to write on the USB key.
In the "Source disc image (.iso) or CD:" sectione When you select the "Other..." button, you browse to the directory where the ISO is, select it, but nothing appears in the box.
The "Make startup disk" does not become enabled.
I am unable to create a live USB key.

Sorry it was my fault!
Did not have permission on the ISO file, I had downloaded it as another user, had to chown to my user, not I am able to select the ISO and create the live USB key.

I have this problem with Kubuntu 18.10. I checked the permissions, and the iso is owned by me and my group. Because I can't select the iso I can't make a usable USB distribution stick. I am able to create USB sticks on another computer running and earlier version of Linux Mint and USB-creator.
