When another Spark user clicks/focuses the chat window Spark will blink in the taskbar. That is what I think is happening, here is a more detailed description:
Say I send a message to another person and then close the chat window. If that other person focuses on the chat window, it will blink my taskbar as if they sent me a message when they didn't. I have to click or close it to turn it off. But as soon as they click or focus on it again it blinks for me again even if they didn't type anything. I'd like it to only blink if they sent a message, not simply focus on the chat window. Does anyone else have this issue?
