What did the Ignore button do in Windows 3.1?

Now, your reaction to this might be, “How could this possibly work? You are just randomly ignoring instructions!” But the strange thing is, this idea was so crazy it actually worked, or at least worked a lot of the time. You might have to hit Ignore a dozen times, but there’s a good chance that eventually the bad values in the registers will get overwritten by good values (and it probably won’t take long because the 8086 has so few registers), and the program will continue seemingly-normally.
