I'm looking for a program that will monitor one possess running on my computer and if the CPU% changes at all it gives me a signal. The signal has to be discreet, like turning the center of the icon for the volume control in the system tray a different color, or making a small section (1x1) on the monitor red. I would like the signal to turn off 5 sec after the CPU for the selected proses drops back down to 0%. I want the program to come into focus with a series of key commands and I would like it to be 100% hidden unless the key command is hit (i.e. insert+home+page up).
I would like this program to be a U3 program.
