Floyd, at least the "warts" you discussed here are software issues that can
likely be resolved with a firmware upgrade -- without the need to climb any
towers!   That's acceptable to me, and to most.  Microsoft has released
stuff after years of development that still didn't work right.  I'd rather
have software "issues" than hardware ones....-WB2WIK/6
