I thought it might be something of that general nature.  I wonder, is there some strategic place where I might put a 'sleep' to let things sort themselves out?  Probably only would take a millisecond or two.  Like after 'zcurses end' or something?  It's always on return, never within the executing program.  As to the strings, within the rules I mentioned the numbers vary:  0;22;3m 0;18;10m 0;15;14m... and so on, so any exact meaning isn't likely to be found.  It seems random, like a dangling pointer error.
