Well it happened with Lottie the other day and she says her PM are less than mine! (approx 50)
Now on the same day I sent about 7 or 8 to Dinx and had no problems. About 5 to Lottie, but then it froze!
Still cant send to Lottie. And yes we are chatting on MSN etc.!!
So it cant be that we have reached a limit between persons. So there must be a gliche in there somewhere guys!
