Minor Bug - 'Enter' key doesn't work in some boxes

[Gabriel-x42]

Bug Description:
In some confirmation boxes the enter key does not close it.
Here are the places I have found so far that do not close when pressing enter.

1. 'Create Wallet' window
2. 'Secret Words' window
3. 'Confirm Secret Words' window
4. The 'Create Wallet' confirmation window (which by the why should have its title changed to 'Wallet Successfully Created' or something similar to that.
   
5. 'Receive'windows inside the wallet
   

Expected Behavior:
When clicking the enter key on such windows they should confirm and/or close.

Desktop (please complete the following information if applicable):
OS: Windows 10 Enterprise
