When remotely logging in as user tc using ssh dropbear server and putty client after the tinycore system has been put back to the login state (exit to prompt and exit again) the remote login dialog stops responding and requires a CNT-C to regain control. Meanwhile the tinycore system has loaded the tc user environment including xvisa and then exits upon CNT-C back to the login state. At this point the system functions normally.
edit:
I should also mention I am using root and tc passwords.

Exit to prompt (user tc) also encounters the same problem as described above.
