[Elecraft] How do unrelated features get broken?

[george fritkin]

One of my  programmer employees once said to me when I asked why is this beta taking so long to clear...he said...." It takes longer to debug software than to write it".  AMEN!!

LOL Wayne, the day when programmers ARE NOT human is the day we had all

Even though features may not be related, one can cause side-effects in
another due to unintentional modification of variables. Of course we
jump through a lot of hoops to avoid this, but programmers are
(unfortunately) human.
