Interestingly, there has been much discussion here as to whether it is a bug.

One faction feels that the purpose of catchup is to protect the preset settings from change, whether deliberate or accidental.

The other faction thinks that the purpose of catchup is to avoid abrupt changes due to, for example, moving a knob which is not pointing at the current value.

So, no cigar until we get a conclusion. What do people out there think ?
