How to avoid it

I bought a new laptop, and I seem to have a problem with opening an engine. I have Houdini 1.5, and every time I switch it on to analyse a more complicated position, everything hangs, and when I open Windows task manager, it shows 99% processor use. I am forced to switch everything off. How to avoid it?

I have Intel i5, 2.3 GHz so I don't think that's the problem.

Tricky question.

Try lowering the engine's priority:

Are you sure it's the latest edition of Houdini 1.5?

I had the same problem with the 1st version, it had a known bug.

I have CB 2009 and it doesn't seem to have such an option.

My version is Houdini_15a_w32_p2. Is it the one with the bug? If yes, I'll install a newer one. But it worked fine on my old computer.

Anyway, using 99% CPU is a good thing. Chess engines are programs that want to calculate as much as they possibly can and are supposed to keep the CPU occupied all of the time.

But the user interface should have a higher priority, so that you can still do things.
