	Well...  yes, but...  it's wide open for a couple of other attack
methods.  If you run the "native" 95/NT executable, the exploits will lock
you up cold or do other nasties.

	Doesn't happen under OS/2, for a couple of reasons.  #1 is that the
system actually comparmentalizes running programs.  #2 is that it's a JAVA
client, so there isn't much it can exploit other than memory

	If you're on ICQ (I'm 8094267) you should consider using the Java
client rather than an executable.

	The IBM stack is solid.  ATM machines use it, so it's been looked
at inside out and upside down for security holes.
