Okay. I'm using Windows2000 on my mame machine, and I've got a shortcut for MAME32 in my startup folder, and when I boot my machine up, sure enough, it starts up MAME32...the only problem is that the mame3 window isn't "selected"...the window's title bar is gray, not blue, in other words. So I can't really navigate MAME32 until I "select" the window by clicking on it.
Any idea how to alleviate this problem (and please, don't say "Don't use MAME32.")
