When switching applications from MacSSH to one that does
NOT have a window covering the MacSSH window, the cursor
disappears. When clicking back to MacSSH, since the
window was not obscured, the cursor is not redrawn.
Then pressing return at a prompt causes the cursor to be
drawn both where it now is, and where it used to be,
probably because in trying to erase the cursor from its
previous location it is actually being drawn instead.
I'm using Block cursor, no blinking, MacSSH 2.1b5 PPC,
