Open process viewer and you will find out that this app uses a whole LOT of CPU. It is also irritating after using it for about 1/2 hr in Photoshop. It takes up real estate and it's distracting. Each time CPU use increases, so too does this app blossom in CPU usage. Simply dragging you mouse across the dock back and forth increases the amount of CPU this app uses to monitor CPU. Use the CPU Monitor in the far less obtrusive and transparent bar mode and view processes and disc use in process viewer. I love Candy Bar and this is a disappointment coming from IconFactory.
