How can I turn off /Pin Connection/ completely

[Deyan]

I am logging on 20 different machines in day to day basis opening a bunch of file for the most of them. When I close PL/SQL DEV without pinning ANY connection, in the next session they are automatically pinned and these that are, require me to enter password, otherwise the app crashes. I am expecting when I do not pin any connection to any of the files I am working on, all of them to not get automatically pinned, regarding that I've already turned off the option. For connecting I am using the KEY icon.

How can I completely turn of the "Pin connection option" ?
I am using version of PL/SQL DEV 12.0.7.1837

I always start from a shortcut containing a logon, e.g.

plsqldev.exe userid=username/pw@sid

There is also a "nologon" option:

plsqldev.exe nologon

See the section "Command-line parameters" in the user guide (37.4 in the PL/SQL Developer 14 user guide).
