CCleaner not removing Comodo Dragon browser history

Hi

I use Comodo Dragon (tweaked version of Google Chrome) for my browsing but i've noticed that ccleaner doesn't remove dragon history and cookies despite running latest version of ccleaner. Any idea what's wrong? On Piriform's website it says ccleaner is compatible with Chrome so not sure why it's not working with Dragon.

Cheers :)

ccleaner only cleans the default directories. So alternate builds (such as palemoon for firefox as of 3.6.6) do not get cleaned.
