when I use google talk the picture droops (slips?) down on the left hand side in both the small window where you see yourself and in the picture the person I'm speaking to sees. I can fix it by touching the screen and sliding it back into the right position but it just does it again. If I don't move it back it keeps going and can slip almost completely out of view. it is the most annoying, wierd thing. anyone else had this problem with video chats?
