If the previous posts don't help you, you might want to elaborate on your question a little. Any specific application? Are all you applications 'not findable'? I suspect you may be downloading a bunch of command line applications. There are a few dotted around. If that is the case, you can probably only get to these through X terminal - however it my mean that they aren't quite what you are expecting if you don't know how to run them. Obviously I might be leading you off on one there, but let us know some of the applications and we might be able to tell you if you have something wrong, or if it is just one of the issues previously mentioned. All the best with it anyway!
