Every once in a while, I will get signed out of Messages (which I use to interface with my Google Talk account) due to connectivity issues. If this happens when I am having a conversation with someone, the messages the person sends to me while I am offline are not displayed once I sign back in to Messages. Signing in to Gmail via the web interface and checking the "Chats" folder confirms that I the person I was talking to sent me some messages that I missed.
Have you also experienced this behavior, and are there are fixes?
Thanks for your help.
