One of the mechanisms Babylon-Pro employs in order to recognize on-screen terms requires about 30 minutes CPU to "learn" the client system. If this process is not finished when you close Babylon, it will continue from where it was interrupted the next time Babylon-Pro is activated. In both these cases Babylon-Pro is running at a very low priority, which means that if there is ANY other program that needs CPU it will get it. When you see that Babylon-Pro is taking 100% CPU that means that nothing else is using your CPU, and therefore Babylon-Pro takes all of it.
This property controls the time Babylon-Pro will spend to "learn" the client system. If optimization target level is set to "low", Babylon-Pro will not perform any optimization. In some cases, Babylon-Pro might not recognize a word on the screen, because this optimization was not performed. If the level is set to "High", it will perform all possible optimizations, but will take longer to "learn" the system.
