Treat all objects as unfilled.

Hi

Got new laptop with windows 10 and x5 doesn't work with it so got X7 student and Home even though I was happy with X5.

Anyway Corel, as always, loads with'treat all objects as filled' and I want to switch it to 'treat all objects as unfilled' but can't for life of me find how to change it, help please.

Thanks

Ian
