Bug report:
When I use File > Export from a Query window, it's clearly trying to make a CSV. The suggested filename is suffixed with .csv.
The problem is the semicolon character is selected by default. That is not CSV. Please change this so the comma is the default delimiter.
Now, I understand semicolon is the standard in certain regions (e.g., France?), but the vast majority of cases, comma is the norm. If semicolon is selected by default, it should only be because regional OS settings are detected that recommend this.
