[...] You are making an incorrect assumption, that the only time you want to trap this combination is when the machine "locks up." Be aware that people use computers for many differt things. For example, I use a PC to gather data at a telescope, in real time, and I don't want ctrl-alt-del or ^C or ctrl-PrtSc to bomb the real-time program. There is only one keystroke combination that will halt the program; all the others are trapped. This decision is a result of sad experience in the past. -- Ed Nather Astronomy Dept, U of Texas @ Austin
