GEORGEW  I would avoid this program like the plague. It has corrupted three of my hard drives and could not bring any of them back to life. I had to use the Apple Disk Utility to get them back working. Stick with it, you are safer.  
(Version 2.1.1)

GEORGEW  Nice program for a simple task and does the job well. My only complaint is their registration. You do not get a number, but a special file to register the program, so if you get a new computer or hard drive and you go to install it, you will not have anything to register it even though you paid for the program. This is a form of DRM that some programmers are adopting as their registration policy. Just like DRM for music, it stinks and users should protest this form of control for what you and paid.  
(Version 1.1.2)

GEORGEW  Works great, but has view issues. It only activates on the main monitor and is not active on a second monitor. When you are using spaces and you show all of them to, lets say, move a document window from one space to another, you can accidently grab the curtain and it moves. It should stay put in this mode. When activated, it shows the current application documents but hides any others. I want it to hide just the desktop.  
(Version 1.1)

GEORGE26  tried this version, but it still has connection problems with the api; not much use until it works  
(Version 1.1)

GEORGE26  I went further with the CPU hog issue by monitoring CleanApp in the Apple Activity Monitor deeper to see its behavior over time. When I first noticed it hogging the CPU (at the time was 100% of one core) it remained at that level for more than 30 minutes when I finally just quit the daemon.

While the explanation that it is waiting for idle time to do its work may be a noble thought, taking this much time to simply log events is far, far too consuming of CPU time is out of proportion with the task, unless is it writing a novel. Something is still wrong and the developer needs to fix/improve that aspect of the program.  
(Version 3.0b2)

GEORGE26  I tried this new version and it exhibits the same traits of the old ones in terms of memory and CPU time. The worst part is the daemon that consistently takes up 100% of one of my four cores of processors and sometimes much of the others on a MacPro, even when my computer is not in use. Until this is fixed I cannot afford to devote that much CPU time to something that is supposed to be just tracking software installs.  
(Version 3.0b1)

GEORGE26  If your computer is asleep, you have to use the Power Management feature to have your computer wake up a few minutes before an alarm for it to work. This is a real hassle, so I am using Awaken instead. I like the extra features it has over Awaken, but having to set and coordinate two time settings is a huge inconvenience so I will not use it as it is.
