Oh, hum.  Could be.  The ANSI sequence sent during initialization is:

	\033e\033%@\033)0\033(B\033[?25l\033[2J

The \033e looks like a bug; it probably should have been \033c (reset 
terminal).   It might be that that is what is biting you?  You could 
change that on line 352 of com32/menu/menumain.c.

\033%@\033)0\033(B sets the character set (IBM CP 437), and \033[?25l 
turns off the visible cursor.

On exit it sends:

	\033[?25h

... to turn the cursor back on.
