Well, there IS a better way than fiddling with the colors.  Trap the int 11h   
interrupts and do send ANSI a cursor position report.  If your ISR is not  
executed, ANSI.SYS (or one of the mutants) is loaded.  After you're done with   
the test, remove your int 11 ISR.

...You trust them with your fortunes, you let them guard your lives
