Programm doesnt change image on select

[mealstrom]

I've got this situation:
Files:
~/Downloads/iso1.iso
~/Downloads/images/iso2.iso
and usb flashdrive connected

When i've lunched usb-creator, iso1 was automatically select by program. When i've changed it to iso2 -- and press ok, nothing had been changed. If i move iso1 to folder with iso2 then there is no autoselected files on programm start and everething works fine.
