I suppose yuo both have and use Plus!, right ?
If you do... then i'd suggest...
You should try reseting Plus settings on Saras pc account because she might have set some sound or whatever notification functions to occure whenever Jortan signs in or talks to her etc... so Plus then freezes msn
Out of the blue what i can think of is that she might have set a custom sound to play whenever a notification regarding Jordan should occure, that is not properly supported/handled by plus, which produces this effect.
So try deleting/reseting her Plus account settings on her computer and see if this fixes it...
As yuo know signing in with Jordans account from teh same pc will load the default settings for Jordans account therefore not produce the same effect (which supports the thought above)
