Intel test never inform the latest driver, install the real latest is always a manual process, is a manual process always.
You can check what I said is correct checking the driver date of your current installed driver, and checking the release date of latest available on intel site. Anyway no guarantees that update fix the issue and is up to you install or not the latest driver, and I not insist more in this.
About Cantabile, In some moment I contact to they so they can check if can do something, this not is a BUG from Chameleon.
"another question.... what is the difference between Little Handler and Big Handler?"
Make reference to the object handles, I correct the word in the next update.
Create a button on screen, you see 8 square handles, for resize the object, now select little handles and select again the object.
A fail from my English, please apologize, if ix that soon.
