A number of different Alt+Tab switcher replacement apps have been developed for XP, such as TaskSwitchXP. I've also written one of my own, which I've used for years. Unfortunately, I've found that on Windows 7 these tools don't work anymore. The problem is that they can no longer register Alt+Tab as a hotkey, because it's already registered (presumably by Explorer). As best I can tell, on XP the default switcher did not use the regular RegisterHotKey API, but now it does.
Does anybody know of a workaround for this, or an Alt+Tab replacement that works on Windows 7? I know they've spiffed up the default one and added the 3D flip switcher (Win+Tab), but I'd still like to be able to replace this with something that works better for me.
