CCleaner 4.08 hanging

I've just installed this version and CCleaner hangs when the cleaning is showing Firefox>Internet History (24% through cleaning).

It's hogging 50% of the CPU. I have to use Process Explorer/Task Manager to shut CCleaner down.

I went back to 4.07 and CCleaner finishes to 100%.

Using Windows XP SP3 & Firefox 25.0.1.
