I'm probably not describing it very well. But I'm not putting it into sleep mode but when I hit the power button it doesn't power down straight away. First Windows closes all its apps, then Windows shuts down, finally the computer powers down. It behaves just like you chose Shut-Down from the start menu. When I do that with MameWah running it shuts down just fine. But when Mamewah is running Mame then I get a dialog saying the application not responding....it also has a button labeled "End now". I'm guessing that either Mame does not shut down properly in response to a Windows message to quit, or somehow MameWah is intercepting the message and not passing it along to Mame. Tonight I'll try hitting power with just mame running without Mamewah to see if that narrows things down.
Sorry to be so confusing...its been a couple of years since I've done any programming and the Windows messaging model has gotten a little blurry.
Thanks,
Rob
