Hotkey for undo doesn't work. Tried in notepad. Tried laptop keyboard and external keyboard. Tried changing system locale and keyboard in Regional control panel. Tried left and right control keys. In a software i use often (Eclipse the java IDE), i went into the menu where you assign hotkeys. I tried ctrl+z and it doesnt recognize that I'm pressing Z if i hold control. Of course the Z key is recognized, and the control key is recognized. Just not ctrl+z. Running windows vista on a dell latitude d830, brand new laptop.
