I was downloading some updates earlier and an error popped up saying:
See attachment for a screenshot.Could not grab you mouse.
A malicious client may be eavesdropping on your session or you may have just clicked a menu or some application just decided to get focus.
Should I be worried? I quickly Googled it and some sites say it's just a bug with the update manager, but I don't want to risk being hacked etc.
Is this safe to ignore, and if not what do I do? I'm using Ubuntu 9.04.
