Thanks for the heads up, Bill. Actually, I'd tested it and did have the ampersand (@) in the test. Just forgot it here:-(. I should also thank you for the constant names, too. When the original post came up, I looked at the SystemParametersInfo function, but couldn't find the constants that would get or set the keyboard state. It's used in my Disable/Enable screen saver program that's avaiable here on the UT. The fact that I had worked with this function before was one reason I was able to get it to work.
