I have noticed this for some time, but just now thought of reporting it. When I have iCam open and viewing the View Motion Events, if a pop up message appears for say CNN, Sports Center or API, the screen then reverts to split out with the titles of each camera. The Motion events are still there and can be selected. You just see a ghost background of the titles of the cameras. I have 6 cameras setup and so it divides the screen into the six quadrants. When viewing the motion camera images the six quadrants are still there with the camera titles. It just a little annoying. I can send some pictures of what it looks like if you wish.
