It would probably be better to assign the string to a variable and then
pass the address of the string variable to the MUI command. I think the
problem is that when you pass a string directly it is only put into the
temporary string buffer (and overwritten later - which is why all the
bubbles are empty).
Null(xxx) just allocates a new string in memory and returns a pointer to
it. It won't be freed until the program exits. Plus you can't change the
strings as easiyl without using a variable (*cough* localisation *cough*).
