That's the bizzare thing... I tried pressing control after my program ran
to snap the computer out of it, but it didn't work.  However, if I run the
program again, (yes, with control F9), every once ina while (random), the
program will restore everything to its normal state.  But, if I just
accepted all of  this, "Hello World" development would take 3 months.
