I have a strange problem, and I'm really hoping someone here can provide a clue. A while ago I installed an obscure Windows 7 utility, which I used to set Ctrl + Down as a hotkey for "minimize all" (aka "show desktop"). I uninstalled the utility some time ago, but the hotkey remained in effect. I really need to find some way to get rid of it, because it's interfering with my work. I've gone through my installed programs, startup items, and running processes, and can't find anything unusual. I don't have the original install files for the utility, and can't find where I got it from. My question is, is there some registry key, or something else native to Windows 7, where this hotkey might have gotten set? Or would it HAVE TO be a third-party application that's still causing it? Is there any sort of tracing application I could try, to record which process is hooking Ctrl + Down when it's used? I'm desperate and will appreciate any brainstorming. Thanks!!
