wow.. sorry. lol.. i didnt fully read your reply
i read the first line, and didnt even see a 2nd line! i really need some sleep
a terminal is like a command prompt.. its like dos, lets say. if your in windows and choose 'run' and type 'cmd' it is something like that (not really though
since your using konquerer, i guess your using KDE as your desktop environment.. in the main menu, there should be a 'terminal' or 'k-terminal' or something similar SOMEWHERE in the list.. maybe in system or system tools or something? i dont use kde so i dont know where/what its called.
once that is opened it will let you type in commands rather than run a program from your KDE GUI.. type the name of the program your trying to launch, ie: type 'konquerer' and hit enter.. what output is displayed if any? or does that hang too?
