llDialog not displaying in other sim

I am trying to use llDialog to notify me that llInstantMessage has placed a message in the chat window. This is important to I keep missing messages that llInstantMessage is sending. This works fine if the object touched to send the message is in the same sim as me. If I am in a different sim than the object touched to send the message, the client does not display the llDialog. Is there a fix for this?


Example:


if (online) {
llInstantMessage(llGetOwner(), name + ": " + message);
llSay(0, "Thank you, " + name + ", your message has been sent.";
llDialog(llGetOwner(),name+" is sending you a message.", ["OK"], 12345);
}

I was going to say that llDialog won't work at all across regions but apparently there is some small print It still doesn't look very fool-proof though.
