I am running CIS on a new computer with Windows 8.1 and I am having internet problems. With CIS on my internet searches by way of Yahoo come out looking like a typed page with lines typed over the top of each other. I keep getting prompts that to run video such as youtube I need to install a new version of Adobe Flash Player. When I try to do that, it never installs and runs correctly. When I close CIS and browse the internet with explorer I have no problems at all. Are there setting or compatibility issues with Windows 8.1?
