**Short description of error**
Default button in File Browser does not always listen to the Return / Enter key
**Exact steps for others to reproduce the error**
I have demonstrated this bug / problem to @Severin in person, so he already knows about this bug, he just wanted me to write a few lines into the bug reporting system as a reminder.
There is no fixed case as to when this happens exactly, but about 50 percent of the time when a File Browser is there for opening / saving files and a filename is entered into the appropriate field, Blender will not listen to the Return / Enter key to continue and do what you had in mind.
Only when one clicks on the default button itself, will Blender carry out the request to "Save" / "Open" or similar command needed at that moment.
