That is extremely odd.  I'm wondering if rxvt doesn't implement some of 
the mode setting escape sequences that the menu system uses, or does so 
incorrectly.

The fact that you're getting the proper background color indicates that 
*something* is working right.

I would try to seriously lower the baud rate (to, say, 2400) just to 
rule out signal integrity problems or buffering issues.
