Description Alexander Mentyu 2017-08-01 08:16:49 UTC

Steps to reproduce:
1. Launch the app with USB device inserted.
2. Click on 'Open image file' button.
3. Choose known distro image.
4. Wait for 'ISO verification' process to finish.
5. Reject 'SHA256 checksum' popup window or enter empty/wrong checksum in it.
6. Take a look at 'Write' button - it should be disabled.
7. Press 'Refresh the list' button - and 'Write' button should become active - and thus you bypass it.

You can bypass restriction also inserting USB drive after rejecting 'SHA256 checksum' popup window or after entering empty/wrong checksum in it.
