Proximity of changing UI elements

The issue is that "Refresh" is shown in some situations, but depending on what you do it disappears and is replaced by, in the exact same position, the "Nest Related Files" icon. This in-situ replacement usually happens when you click different files or elements, but can also occur when the focus changes - such as when you click the "refresh" icon. As soon as you click the icon it changes from Refresh to "nest related files" and you have to wait while VS spends 5 minutes working out who belongs to whom.
