A while ago, I looked into Desktop Managers for my laptop. I tried a few of the Desktop Manager in their demo modes, but I didn't find any that I really liked, and then deleted the demos.
Yesterday, I got an email from You Software, announcing their You Control: Desktop software. I figured that they just came out with a new version, so I wanted to check it out. After I downloaded the demo, and tried to launch it, it claimed that my demo period had expired, even though I just installed this new version.
I seems that they use the date that I checked out the old version as the start date of my demo period for the new version. Maybe this was unintentional, but I am really unlikely to purchase this software, especially if I don't know if it will work for me.
