With "Close if no tabs exist" UNCHECKED, one tab (the default TCC12) ... Tabs\DetachTab ... the console detaches/appears and TCMD has no tabs. If (1) I issue EXIT in the console TCC.EXE disappears from TaskMgr but the console window is not destroyed!!! It's still visible and can be minimized, maximized, and restored. If (2, instead or subsequent to 1) I "X" the console, both TCC and TCMD disappear. Reproduced on two (XPSP3) computers.
