Thanks Jean Louis for the detailed information. I will take a look this
afternoon (still at work this morning).
In the meantime, one more question. Have you ever seen this behavior when
bandhopping? I ask this question because I have never seen this behavior, but I
am always bandhopping, so I wonder if this is restricted to the “no hopping”
situation.
