So setting [min|max]Resolution in the options passed to an overlay should switch the overlay on/off when it goes in range/out of range.
I have collegues here that have problems with doing that. They had to resort to doing: var layer = new ... layer.maxResolution = value; layer.alwaysInRange = false; to make things work as expected. I'll check with them if we can come up with an actual test case for this.
