It is actually a problem with the website, not your computer or the TechTracker software, which means it is affecting everyone but is something that they can fix without you needing to reinstall anything. I will send them an alert now...hopefully they can get it fixed tomorrow.
I just signed up for techTracker Plus and the "Expand all info & settings" or the "Info & settings" doesn't work when I click on them to hide apps. It worked once and hasn't worked since. I'm using an iMac 2 Gh Intel Core 2 Duo, OS 10.6.7, with 2 GB of Ram. I trashed Tectracker Plus 3 times and reinstalled it to no avail. I even ran DiskWarrior but this didn't help either.
