PowerFreeze 1.2 - lets you create your own package-freezing setups.So you can build for example a setup especialy for internet-access or whatever you want. 

What's the reason for using PowerFreeze? Every activated package needs some useful heap-space. The more package you have installed on your Newton, the less the free heap-space is! Know you have two possibilities to solve this kind of problem. First, you freeze the unused packages manually (that's really hard work, because you have to do it everytime) or you use PowerFreeze and define some setups. Every time you want to activate a special setup, start PowerFreeze, select your setup and activate it. That's all!
