Howdy Y'all I'm a VB Programmer trying to pick up on Linux & C++... When a program goes into a loop, like when a program crashes, the computer will act strange... Things will be extremely slow, or will not work, etc... If you check with 'top' & see what's eating up your cpu, like Andrei suggested, make sure you know what the process is that is eating up the cpu time... If you are not familiar with it, see what others may know.... Hope This Helps, Brant Wells
