>I am attempting to troubleshoot a VFP 9 program with an open debugger. This is Windows 10. But when I press on F8 (go into the code), some Project window opens. When I press on F6, it appears that some brightness slider appears. These appear to be native F10 features. How can I disable them so that I can go through the debuger?

See attached image how my keyboard looks like, perhaps you have a similar key to toggle the keys.
