"selection interface" ? I'd rather have the original interface...

It is caused by the new Neural filter.

HERE IS A WORKAROUND:
- disable the neural net filter
- cut as expected
- close the cut
- re-enable the neural net filter

This also uncovers BUG #2:
When saved (as a last score before a crash for example) with an open cut, trying to load it will crash the client as filters are anabled upon loading the last solution.

- if this happens, delete the autosave-it solution and autosave recentbest solutions, then restart the client.

BUG.

Fixed in latest update
