When accessing a Unix based system through X11, how do I open new windows?  Like.. when I run a program, the program starts up, but I am unable to use the existing window?  Do I have to open up a new window and run ssh again whenever I want to run another program?  ALso, when working in this way, all files are saved on the remote computer correct?  Thanks in advance.
