How To Get Aquire / Twain Working With Corel X4 On Windows 10?

I had CoreDraw Graphics Suite XI installed on Windows 7 and upgraded to Windows 10. I have tried various compatibility modes and the compatibility mode for Windows 7 seems my best option. The programme appears to run and work fine except for two things. I cannot see the file menu bar letters until I hover my mouse over them*. I can live with that. However, the Aquire by scanner option is greyed out. Using Control Q doesn't work either. I do a very lot of scanning directly into Draw so I would like to get that working again if possible. Has anyone figured out a registry hack or a setting somewhere that might work to get the Aquire by TWAIN option working? Your advice will be appreciated.

Kind regards

Chris

* In XP compatibility mode I can see the file menu bar letters but the work space flashes blue every time I click my mouse on it which is unacceptable.
