Unable to set NULL in Foreign key field

Hey,

So when I try to set a value in the Data tab for a foreign key value I am presented with a dropdown with all the values of the field that foreign key links to.

This is all very nice, but the problem is that I have the "Allow NULL" set for that foreign key and from the Data tab there doesn't seem a way to set that field back to NULL.

I am using the latest version (9.2.0.4974)

You should be able to focus the field and press Shift+Ctrl+N (or rightclick > "Insert value" > "NULL"). Do not enter the editing mode in that field!

You are correct, but wouldn't it be easier just to set an empty line in the select (or something with (NULL))?
