I recently purchased BeeJive, and have never seen this before, but;
When you receive a message with the LED going, has your screen ever flickered?
I recently have been receiving messages, and my screen flickers from time to time. It'll go black for a flash and back to normal again. I've only seen it twice tonight, but am hoping it doesn't become an issue in the future.
I'm using an 8900 and hoping for an answer from 8900 users, but if you have another device and this has happened to you, please feel free to chime in.
