A couple of years ago I used a program by the name of screen that actually had borders on screen between multiple tiled windows. Is this the same program ? That is, can I see several sessions on the same screen ? -- Nirad Sharma (exnirad@brolga.cc.uq.oz.au) Phone : (+61 7) 365 7575 Systems Programmer Fax : (+61 7) 365 7099 Continuing Education Unit The University of Queensland.
