How to scan multiple images and stop TWAIN scanner closing after every scan?

I was using CorelDraw X4 for many years running Win 7 Ultimate 32 bit and had it configured with my Epson V700 scanner to be able to scan multiple images without closing. It would only close when I clicked "close" in the scanner interface. I recently upgraded to Win 7 64 bit and I now have the default settings that the Twain scanner driver will close after every scan which makes scanning very slow. I can't remember how I configured it before. Does anyone know if there is a setting in CorelDraw preferences or the scanner preferences to allow multiple scans without closing every time? Yor advice would be appreciated.

Kind regards
