Have upgraded to Windows 10 from 7. The Coffeecup HTML Editor is now slow to open.

The box which says do you wish to allow this app to make changes to your computer comes up quickly.

Then the circle and cursor start to shudder and it takes 12 secs for editor to open.

Also when I load a project I get:
Error restoring device context.

Coffeecup believe the issue is because I have not done a clean install.
