What desktop calendar programs would you recommend?

I use Rainlendar and I like it because it is simple and works fine. I don’t really use the “calendar” part, I really just want a program that is locked to my desktop and where I can put my TO DO list thus getting alarms for certain events and being able to cancel out accomplished tasks. The cool thing about Rainlendar is that people actually make skins for it and post it on the site so you have tons of options. I just wanted to make sure I wasn’t missing out on a better TO DO list/desktop calendar program. My only problem with Rainlendar is that when I minimize all windows (Win key + D), the rainlendar one gets minimized too instead of staying locked to the desktop. I have already googled this so I would appreciate answers about programs that you yourself have used and your experiences. Thanks!

Edit – i forgot to mention I am on Windows XP
