I have this weird thing happening every now and then. A dialog box pops up, and then disappears within the blink of an eye. It happens so quickly that all I'm able to discern is what looks to be the yellow icon with an exclamation mark in it. It's obviously some kind of error or warning. It happens at random, perhaps two, three times a day, and I have no way of knowing when it occurs. What information it conveys, is a mystery, due to its hyperdrive speed. I have no idea what it is and it's starting to annoy me. I've tried looking in Console, but I have no idea what to look for. Can anyone help shed some light?
