Eclipse Randomly Does Not Recognize Arrow Keys or Backspace, Spacebar etc

I haven't worked with Aptana in a long time, but I've used Eclipse quite a bit, and I believe the tab-switching is bound to Ctrl+PgUp (or PgDown) by default. I just recently installed Galileo, and used this as an opportunity to try rebinding to Ctrl+Tab, but didn't have any luck.

I know I got this to work on previous versions of Eclipse (at least Europa, and possibly Ganymede), but am not certain why it's not working in Galileo. Regardless, here's how to find the key-bindings in an Eclipse install (I would assume Aptana uses these bindings as well):

Windows->Preferences->General->Keys

From there you can try filtering the key-binding you're looking for (e.g. "tabs" or something) and input whatever combo you want.

I would also recommend searching for the key-combo you're going to use to make sure it's not already in use. If it is, you'll want to re-bind the conflicting binding, so they don't collide.

The feature that provides the functionality of what you are experiencing is called StickyKeys. It's not new to Windows 7, and it has been in since at least Windows XP that I know of, possibly earlier.

To disable in Windows 7: Menu Start -> Control Panel -> Ease of Access -> Change how your keyboard works (or make the keyboard easier to use) ->

All your settings are in here. I personally untick everything when I build a new PC. Make sure nothing is ticked and also go into setup StickyKeys and untick anything in here.

I cannot explain why coming out of sleep is causing this, but hopefully this should stop it from happening.
