Background removal from photo using VERTUS FLUID MASK

I need to do a fair amount of deep etching of peoples photographs - removing the background from these photos using cut out lab is very laborious - specially as it gives many problems removing the background from between hair blowing in the wind.

The program Vertus Fluid Mask apparently does a very good and fast job, had a look at their site, seems very good, but it is made to be used with photoshop a program I do not know. They sell it as a stand alone product as well -

Has anyone experience using this product? If not Has anyone experience with a product that works well with Corel graphics suite?

Anxious to hear,

Hans
