You certainly can uninstall earlier version of SOnar if you want to. They will coexist with Sonar 4. You need jaws 5.1, 6, or 6.1.

First of all, which version of JAWS do I need to use? Also, do I uninstall the previous version of Caketalking 3.1 and Sonar 2.2? Does it matter, because I'm thinking that if I'm not using them that they're taking up space on the hard drive that I can free up for something else. Thanks
