I'm using Windows 7 with Dexpot virtual window manager and DexGrid plugin and LOVE it! I had set ALT-CTRL-arrow to switch desktops (and ALT-CTRL-SHIFT-arrow to move active window and switch). This was working great for several months, but a few days ago, the switch desktops stopped working. When I went into Dexpot's (excellent) settings page to investigate, the key combination was still there, but had a little warning symbol next to it, implying Dexpot knew something's wrong, but didn't say what. What could've "stolen" that key combination?
I think to install Hotkey Explorer to solve this, but read some (old) iffy reviews about it. Are newer version more reliable? Alternately, would AutoHotKey give me this info? Another app?
note: the (?) in the question title means I'm not sure I stated this correctly: "Dexpot's system-wide hotkey". It also brings up many other completely unrelated questions containing "system-wide", so may throw others off. I'll be happy to edit the title if someone confirms or suggests a better description.
edit: I haven't installed any windows updates before the problem started (I thought there aren't any more since M$ stopped support, no?). Took me some tinkering to figure I installed a bunch of apps recently (more than I'd thought), but since I'm not sure when exactly the problem started, it's hard to pinpoint the guilty one this way :\. I thought I could "steal" it back with Dexpot, but no success. Does that mean an application can make "system-wide" hotkeys and "lock" them? Either way, I'd like to trace the hotkey associations, which should point me straight to the culprit.
