Thunderbird closes instead of minimizing to task bar

When I click on the minimize "-" in top right corner of Thunderbird it does not minimize to the bottom left task bar as other programs do, but instead goes to the system tray (bottom right). Online help suggested I go to "Settings-General-Language and Appearance" and un-check "Hide system window titlebar". This appears to make no difference. How do I get this back to what it used to be?

Thank you so much! Such a simple, obvious solution that worked,as it should. I don't know what changed it, but now fixed.

The following steps might be helpful: "Settings" > "General" > "System Integration" section > untick "When Thunderbird is minimized, move it to the tray".
